Lump on The Lower Left Abdomen Symptom, Causes & Questions

A mass or abdominal lump on the lower left abdomen can most commonly be caused by skin conditions like cysts, abscess, or growth of fatty tissue known as lipoma. If you have a lump that causes pain on the left side of the abdomen, you may also have a hernia or an ovarian cyst if you are female. Read below for more causes and how to treat a lump in the lower left side.

This symptom can also be referred to as: bump on lower left belly

Lower Left Abdominal Lump Explained

The abdomen is separated into four quadrants. The left lower quadrant of the abdomen contains the terminal part of the colon, the ureter of the left kidney, and the iliac fossa (part of the hip bone and pelvis), which is a gateway to the reproductive organs in both men and women.


See this here for a visual representation of these multiple components. Due to its complexity, the lower left abdomen is susceptible to multiple conditions that can have a wide array of symptoms. A lump in this area can be upsetting as it is often associated with symptoms such as [1]:

  • Pain or discomfort
  • Tenderness to the touch
  • Changes in appearance: The lump may undergo changes during activities such as standing, coughing or straining.
  • A burning or aching sensation

Concerning symptoms

New lumps and bumps in the abdomen are also concerning since they can be the initial sign of a cancerous process. Lumps that are hard and rigid and grow in size over time raise suspicion for a tumor while lumps in the lower left abdomen that are easily mobile and can be pushed back in with manual pressure are less concerning. However, if you are also experiencing fatigue and unexplained weight loss or bloating, you should seek treatment.

Other symptoms

A lump on the lower left abdomen can be associated with additional unpleasant symptoms such as:

If the lump is absent

The lump on your lower left abdomen may not be directly visible. Sometimes it can be better felt while using deep pressure with the fingers around the area you suspect it is located. Thus, if you experience some of the symptoms above but do not visibly see a mass in the lower left quadrant, do not assume there is no problem.

Given that the lower left abdomen is complex and houses various important organs, it is important to make an appointment with your healthcare provider as soon as you notice any of these symptoms.

What Can Cause a Lump on the Lower Left Abdomen?

Because the left lower quadrant of the abdomen is a complex interplay of structures, inflammation, obstruction, cancer or injury to any of its components can result in an abdominal lump [1]. See your physician promptly in order to get the appropriate diagnosis and treatment.

Muscular/Tissue-related causes

A hernia occurs when part of an organ pushes through an opening or weakness in the muscles /tissues that surround it. The protruding organ or tissue can result in a noticeable lump or bulge in the area. Hernias can occur in both men and women and can occur in many different ways, but most commonly hernias happen due to the following processes:

  • Inguinal: In men, this type of hernia often protrudes through a specific structure in the lower abdomen called the inguinal canal where the spermatic cord enters the scrotum [3].
  • Surgical: A surgical incision is essentially the creation of a weakness in the abdominal wall. After surgery, the abdominal wall is closed; however, factors such as weight gain, pregnancy, or excessive activity too soon after the surgical procedure can result in an increase in abdominal pressure and stretching of the incision before it is completely healed. This makes it easy for contents to protrude through the incision, resulting in a hernia.
  • Sports: A sports hernia is a painful injury of the soft tissue that occurs due to sudden changes of direction or intense twisting movements while participating in soccer, basketball or wrestling, for example. Even though a sports hernia may lead to a traditional, abdominal hernia, it is a different injury.

Reproductive Tumors

The reproductive organs in both men and women are within or very close to the lower left quadrant of the abdomen. Growths in these organs whether benign or malignant can often manifest as palpable and visible lumps in the lower left abdomen.

  • Males: In males, the freely mobile testes can develop cancerous growths that can be felt in the lower left abdomen.
  • Females: In females, the ovaries often lie within the lower quadrants of the abdomen. Not only are the ovaries susceptible to cancer, but they can also develop cysts that can grow very large and cause pain in addition to a lump.


An abdominal lump in this area may be due to inflammatory causes, such as:

  • Infectious: Infection of the large intestine by gastrointestinal organisms can cause the formation of abscesses that may result in palpable masses of the lower left abdomen.
  • Dermatologic: Some inflammatory dermatologic conditions have a predilection for specific quadrants of the body. For example, shingles , a painful rash caused by a virus, can localize to the left lower abdomen and causelumps and a rash accompanied by severe pain and itchiness. Furthermore, lumps that arise from the skin or subcutaneous fat in the form of cysts and lipomas can result in lumps in the lower left abdomen.


Trauma to the lower abdomen via a direct blow or motor vehicle accident can cause a lump that is a manifestation of a contusion, also known as a bruise.

8 Possible Lump On The Lower Left Abdomen Conditions

Lipoma is a word that translates as "fatty tumor," but a lipoma is not cancer. It is simply a growth of fat between the muscle layer and the skin above it.

The exact cause is not known. The condition does run in families and is associated with other unusual syndromes such as adiposis dolorosa, which is similar. Lipomas most often appear after age 40.

Symptoms include a soft, easily moveable lump beneath the skin, about two inches across. A lipoma is painless unless its growth is irritating the nerves around it. They are most often found on the back, neck, and abdomen, and sometimes the arms and upper legs.

It is a good idea to have any new or unusual growth checked by a medical provider, just to make certain it is benign.

Diagnosis is made through physical examination, biopsy, and imaging such as ultrasound or CT scan.

Most of the time, treatment is not necessary unless the lipoma is unsightly or is interfering with other structures. It can be removed through surgery or liposuction.

Rarity: Uncommon

Top Symptoms: skin-colored groin bump, marble sized groin lump, small groin lump

Symptoms that always occur with lipoma: skin-colored groin bump

Urgency: Wait and watch

Skin cyst

A cyst is a small sac or lump, filled with fluid, air, fat, or other material, that begins to grow somewhere in the body for no apparent reason. A skin cyst is one that forms just beneath the skin.

It's believed that skin cysts form around trapped keratin cells – the cells that form the relatively tough outer layer of the skin.

These cysts are not contagious.

Anyone can get a skin cyst, but they are most common in those who are over age 18, have acne, or have injured the skin.

Symptoms include the appearance of a small, rounded lump under the skin. Cysts are normally painless unless infected, when they will be reddened and sore and contain pus.

Diagnosis is made through physical examination. A small cyst can be left alone, though if it is unsightly or large enough to interfere with movement it can be removed in a simple procedure done in a doctor's office. An infected cyst must be treated so that the infection does not spread.

Rarity: Common

Top Symptoms: skin-colored armpit bump, marble sized armpit lump, small armpit lump

Symptoms that always occur with skin cyst: skin-colored armpit bump

Urgency: Wait and watch

Ovarian cyst

During her reproductive years, a woman's ovaries release a single egg cell each month. But sometimes the egg remains on the surface of the ovary, where the follicle that enclosed it continues to grow. It then becomes a fluid-filled ovarian cyst.

Ovarian cysts may be caused by hormonal imbalances; by endometriosis tissue, if it attaches to the ovary; and by severe pelvic infections that spread to the ovaries. Cysts may also form during pregnancy.

Small ovarian cysts often cause no symptoms. Larger cysts may cause pelvic pain, backache, unexplained weight gain, abnormal vaginal bleeding, and/or pain during sex. Ovarian cysts are almost never a form of cancer.

Sudden, severe abdominal pain could indicate a ruptured cyst. This is a medical emergency and the patient should go to an emergency room or call 9-1-1.

Diagnosis is made through ultrasound.

Hormonal birth control, such as the pill, injection, or patch, prevents ovulation and therefore prevents the formation of cysts. Surgery to remove the cyst may be necessary in some cases.

Rarity: Rare

Top Symptoms: stomach bloating, vaginal bleeding, pelvis pain, lower abdominal pain, lower back pain

Urgency: Primary care doctor

Skin abscess

A skin abscess is a large pocket of pus that has formed just beneath the skin. It is caused by bacteria getting under the skin, usually through a small cut or scratch, and beginning to multiply. The body fights the invasion with white blood cells, which kill some of the infected tissue but form pus within the cavity that remains.

Symptoms include a large, red, swollen, painful lump of pus anywhere on the body beneath the skin. There may be fever, chills, and body aches from the infection.

If not treated, there is the risk of an abscess enlarging, spreading, and causing serious illness.

Diagnosis is made through physical examination.

A small abscess may heal on its own, through the body's immune system. But some will need to be drained or lanced in a medical provider's office so that the pus can be cleaned out. Antibiotics are usually prescribed.

Keeping the skin clean, and using only clean clothes and towels, will help to make sure that the abscess does not recur.

Rarity: Common

Top Symptoms: rash with bumps or blisters, red rash, red skin bump larger than 1/2 cm in diameter, pus-filled rash, rash

Symptoms that always occur with skin abscess: rash with bumps or blisters

Urgency: Primary care doctor

Tumor of the digestive tract

Gastrointestinal stromal tumors (GISTs) are a very rare type of tumor that originates in the walls of the stomach and small intestine. While these tumors can cause symptoms such as stomach pain and bloody feces, 1/4 of cases have no symptoms and are discovered accidentally.

Rarity: Ultra rare

Top Symptoms: fatigue, nausea, loss of appetite, diarrhea, constipation

Urgency: Primary care doctor

Colonic neoplasm

Colonic neoplasm means "new tissue" growing in the colon, or large intestine. This neoplasm may be either benign (not cancerous) or malignant (cancer.)

The exact cause of any cancer remains unknown. Risk factors seem to be:

Being over fifty years of age.

  • Family history of the disease.
  • A high-fat, low-fiber diet, typical in the modern world
  • Chronic inflammatory diseases of the colon such as Crohn's disease.
  • Smoking and alcohol use.
  • Diabetes, obesity, and inactivity.

The earliest symptoms are usually polyps, small growths within the colon which can be detected on colonoscopy and removed before they can become cancerous. Later symptoms may be unexplained fatigue; change in bowel habits; persistent abdominal discomfort such as gas or cramps; blood in stool; or rectal bleeding.

Diagnosis is made through colonoscopy and sometimes blood testing.

Treatment is done through surgery, which may be minor or extensive; and through chemotherapy with radiation therapy, usually done before and after surgery. Supportive care to keep the patient comfortable is also an important part of treatment.

Rarity: Rare

Top Symptoms: fatigue, stomach bloating, stool changes, diarrhea, constipation

Urgency: Primary care doctor

Boil (furuncle)

A furuncle, also called a boil, is infection of a hair follicle. The infection forms under the skin at the root of the hair and may occur anywhere on the body.

The infection is caused by bacteria, most often Staphylococcus aureus or "staph." Irritation caused by clothes or anything else rubbing the skin can cause the skin to break down and allow bacteria to enter.

Staph bacteria are found everywhere. Frequent and thorough handwashing, and otherwise maintaining cleanliness, will help to prevent its spread.

Most susceptible are those with a weakened immune system; diabetes; and other skin infections.

Symptoms include a single bump under the skin that is swollen, painful, and red, and contains pus.

It is important to treat the boil, since infection can spread into the bloodstream and travel throughout the body.

Diagnosis is made through physical examination and sometimes fluid sample from the boil.

Treatment may involve incision and drainage of the infection, followed by creams to apply to the site of the boil and/or a course of antibiotic medicine.

Rarity: Uncommon

Top Symptoms: pink or red facial bump, small facial lump, painful facial bump, marble sized facial lump, constant skin changes

Symptoms that always occur with boil (furuncle): pink or red facial bump

Symptoms that never occur with boil (furuncle): fever

Urgency: Self-treatment


A dermatofibroma is a common skin growth that usually appears on the lower legs, but may appear anywhere on the body. These growths are benign (noncancerous). Dermatofibromas are most common in adults and are rarely found in children.

Symptoms include a hard, raised growth that is red, pink, ...

How to Treat a Lump on the Lower Left Abdomen

Since the causes of left lower abdominal lumps are varied, it is important to make an appointment with your physician in order to get the proper diagnosis and treatment. Depending on the cause of your symptoms, your physician may suggest:

  • Surgery: If a hernia is causing your condition, your physician may suggest open or non-invasive surgery to relieve discomfort and prevent complications. However, if your hernia is not causing you significant pain or discomfort, your physician may suggest watchful waiting. Some dermatologic conditions such as cysts or neurofibromas can also be removed by surgery [2,5].
  • Antibiotics: If your condition is caused by an inflammatory etiology caused by bacteria, your physician may prescribe specific antibiotics.
  • Cancer Treatment: If your lump and associated symptoms are due to cancer, your physician will discuss treatment options including surgery, radiation or chemotherapy.

FAQs About Lump On The Lower Left Abdomen

Here are some frequently asked questions about lump on the lower left abdomen.

Will a lump on the left lower abdomen affect my sexual function or reproductive capacity?

Often lumps that involve the reproductive organs in men and women can have a negative effect on sexual function. For example, ovarian cysts in women can often be associated with pain during sexual intercourse. In the case of reproductive cancers that require treatment such as chemotherapy and radiation, you may have to have a conversation with your physician about the future of your reproductive capacity. Fortunately, there have been many strides in the fields of oncofertility and preservation of reproductive capacity during cancer treatment.

Can I still exercise with a lump on my left lower abdomen?

Exercise is acceptable if you take precautions to avoid aggravating the abdominal tissues or increasing intra-abdominal pressure. Low-intensity or low-impact exercises such as dancing, walking, or water aerobics may be good options. However, activities such as heavy weightlifting can cause strain in that area and increase pressure in the abdomen causing the lump to bulge unnecessarily. Speak with your physician before beginning an exercise regimen.

When will the lump on my left lower abdomen resolve?

The resolution of a lump on the lower left abdomen will be dependent on the cause. Lumps that are treated with surgical removal have a certain timeline whereas lumps that are the result of a cancerous process will have a completely different timeline.

Is a lump on the left lower abdomen dangerous?

A lump on the left lower abdomen can signify various different conditions. Immediately life-threatening conditions that require emergency medical attention are complications of hernias that are known as incarcerated or strangulated hernias. A hernia is incarcerated when it becomes trapped in the abdominal wall. Incarcerated hernias are dangerous because they can wrap around themselves and cut off blood flow to the trapped tissue. When this occurs, a strangulated hernia results, which can have life-threatening consequences if not treated promptly. Symptoms of these conditions include nausea and/or vomiting, fever, pain that is sudden and increases in intensity, inability to pass gas, severe tenderness when you touch your abdomen or swelling of the abdomen.

Will the lump on my left lower abdomen spread to the other side?

Most causes of lumps in the lower abdomen do not spread in this manner. Even in infectious or inflammatory causes of lumps in this area, spreading to the other side is not common. If you experience spreading of lumps on your body, make an appointment with your doctor promptly.
