The lumps seen in lymphoma occur when cancerous cells accumulate in the lymph nodes, causing them to swell. It is still unclear why some people develop lymphoma and others do not. Both acquired mutations and inherited factors are believed to increase the risk of developing Hodgkin lymphoma and non-Hodgkin lymphoma. There are two types of lymphoma: Hodgkin lymphoma and non-Hodgkin lymphoma. Inherited mutations, which occur far less frequently, are passed down from parents to children and are present in the DNA of all cells at birth. Acquired mutations are caused by normal aging and exposure to carcinogens, such as radiation, certain chemicals, smoking, and some viruses. The genetic mutations that can cause lymphoma may be acquired or inherited. In people with lymphoma, white blood cells known as lymphocytes develop genetic mutations that allow them to grow faster and live longer than healthy cells. Like other types of cancer, lymphoma is caused by genetic mutations that allow cells to divide and grow in a disorganized way.

Lymphoma starts in the lymph nodes and vessels of the lymphatic system. It is believed that genetics may play a role in a person’s likelihood of developing a lipoma. What Causes Lipoma and Lymphoma?īoth lipomas and lymphoma have no identified cause. The symptoms you experience depend on the type of lymphoma you have. Swollen lymph nodes are the most common symptom, and other signs and symptoms include: Lymphoma, on the other hand, comes with a range of symptoms. Lipomas can be painful if they press against a nerve or develop near a joint. Symptoms of Lipoma and LymphomaĪside from the presence of a mass, there are generally no other symptoms that come with lipomas besides possible discomfort. Multiple regions with swollen lymph nodes occur in people with non-Hodgkin lymphoma more frequently than in those with Hodgkin lymphoma. A person with lymphoma may have swollen lymph nodes in just one area or multiple areas (referred to as generalized lymphadenopathy).

Those with lymphoma may experience swollen lymph nodes in the neck, armpits, or groin. Although lipomas can appear anywhere on the body, they typically develop on the arms, shoulders, back, neck, torso, and thighs. Most lipomas are also not painful when touched or moved. Because it’s near the skin’s surface, the mass can be moved around freely. This mass is usually small (less than 2 inches in diameter) and may feel doughlike in texture. With lipomas, you will notice a soft mass on the affected area just under the surface of the skin. What Do Lipomas and Lymphoma Lumps Look and Feel Like? Lipomas are fatty tumors and lymphoma lumps are made up of cancerous cells. The lymph nodes may also swell as a result of lymphoma, producing rubbery, round lumps under the skin. They often become enlarged when a person becomes sick with an infection (during a bad cold, for instance, you may feel a lump somewhere behind and below your ear). Lymph nodes are glands that belong to the lymphatic system. Unlike lipomas, however, these lumps develop as the result of swelling in the lymph nodes. Lymphoma can also manifest with lumps under the skin. In fact, lipomas are generally considered benign (noncancerous).

However, having a lipoma doesn’t always mean that you have cancer. Lipomas can appear in conditions such as liposarcoma (cancer of the fat cells). This growth is mostly made up of adipose tissue (fat cells) and can appear in almost any part of the body. A lipoma is a fatty tumor, or lump, beneath the skin.
