Painless Chest Wall Lump Symptoms

A painless chest wall lump can be a concerning symptom. In the absence of pain, it may be harder to determine changes to the lump over time. However, a lump can signify a serious underlying condition, so it is important to try to keep in mind the following characteristics and consult a medical provider in a timely manner.

For most, a chest wall lump may elicit fears of a cancerous process, especially if they are associated with symptoms such as:

The lump may also be hard, feel rigid or stuck in place, and grow in size over time. If you experience such symptoms in addition to your chest wall lump, make an appointment with your physician promptly.

Less-concerning symptoms

Despite the seriousness of such a finding on your body, there are some signs and symptoms that can be reassuring. For example, chest wall lumps are less concerning if they have the following characteristics:

  • Soft
  • Easily mobile
  • Get smaller in size with rest

Regardless of the specific symptoms you experience, it is always imperative to see a healthcare professional to further investigate your chest wall lump.

Painless Chest Wall Lump Causes

The chest wall is a cavity of bone (including the spine, sternum, and ribs) and muscle that forms a cage around the lungs, heart, and other vital organs. There is also fat and various tissues and vessels that run throughout this area. Conditions that affect these structures can result in chest wall lumps of various etiologies that can be grouped into the following categories:


In general, any growth is the result of cells dividing and growing uncontrollably. Sometimes there is a genetic mutation in DNA or a specific protein or failure in an important checkpoint that results in this unchecked growth. These abnormal cells accumulate to form a noticeable lump, also called a tumor. Tumors can be divided into the following groups [1,2].

  • Benign: A tumor that originates in the bone or muscle of the chest wall that does NOT invade nearby tissues or spread throughout the body is considered benign (harmless). Tumors such as lipomas (tumors of fatty tissues) are often benign.
  • Malignant: A malignant tumor iinvades not only its surrounding tissues but also has the capacity to spread to other parts of the body. Malignant tumors can also be categorized as primary or secondary. Sarcomas (tumors that arise in cartilage, soft tissues or bones) are often malignant. Primary tumors originate in the bone or muscle of the chest wall.Secondary tumorsoriginate elsewhere in the body and metastasize (spread) to the chest wall.


There are many other conditions that can appear as lumps in the chest wall.

  • Dermatologic: Many dermatologic conditions can result in lumps and bumps on the skin throughout the body. For example, cysts are growths that can be filled with fluid, pus, blood or other material. They often feel like small peas under the skin that are painless or smooth to the touch.

  • Infectious: Some bacterial and viral skin infections can result in sequelae that look like growths. For example, some strains of human papillomavirus (HPV) can result in warts or wart-like growths on the skin.

  • Lymphatic: The lymphatic system is an import network of organs, vessels, and glands throughout the body important for immune function. The glands of the system, also called lymph nodes, function to filter and trap viruses, bacteria, and other pathogens before they can spread and infect other parts of the body. There are lymph nodes in the chest wall that can swell in the setting of inflammatory conditions, including infections, that may appear as chest wall lumps.

Painless Chest Wall Lump Treatments, Relief and Prevention

Since the causes of painless chest wall 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 the following [4].

  • Cancer treatment: If your painless chest wall lump and associated symptoms are due to malignant cancer, your physician will discuss treatment options including surgery, radiation or chemotherapy [3].
  • Surgery: Surgery is often an option for benign chest wall growths but also can be considered in removing conditions such as warts or other dermatologic skin problems.
  • Supportive care: For most other causes of chest wall lumps, watching and waiting for the lump to resolve is often a first-line treatment option. Many conditions such as warts and cysts often resolve on their own.

FAQs About Painless Chest Wall Lump

Here are some frequently asked questions about painless chest wall lump.

Will the lump in my chest wall go away on its own?

Depending on the cause, there is a possibility that the lump will go away on its own. If the chest wall lump is a cyst or caused by lymphatic swelling from a transient infection, the likelihood that it will go away on its own is high. However, if the chest wall lump is a benign or malignant tumor, it will not resolve on its own and will require follow-up.

Will the lump become painful?

The chest wall lump may or may not become painful depending on the cause. Some tumors may become painful over time; and although warts and dermatologic conditions such as cysts are usually painless, there is a possibility that they may become painful over time as well.

Is the chest wall lump chronic or temporary?

A chest wall lump may be temporary or chronic depending on the cause. A chronic chest wall lump is more associated with benign or malignant growths whereas temporary lumps are more associated with other causes such as dermatologic skin conditions.

How will the lump affect my daily activities?

A chest wall lump may affect activities such as inhaling and exhaling deeply because a growth within the muscles of the chest wall can impede movement of the chest wall. If your symptoms are due to a malignant process, you may also feel extremely fatigued and unable to carry out normal daily activities.

What can I do to prevent the development of chest wall lumps?

It is very difficult to prevent the development of chest wall lumps. Some chest wall cancers are genetic or hereditary in nature (meaning that they are passed down from family to family). Other causes such as lymph node swelling or dermatologic skin conditions may be prevented with techniques such as proper hand washing and hygiene practices.
