What is a finger lump?
A finger lump is a protuberance or localized area of swelling that can occur anywhere on your finger. Other terms used to describe the various types of finger lumps include bump, nodule, contusion, tumor and cyst. Finger lumps can be caused by any number of conditions, including infections, inflammation, tumors or trauma. Depending on the cause, you might have single or multiple finger lumps that are soft or firm, painful or painless. They may grow rapidly or may not change in size.

If your finger lump forms due to local inflammation of the finger joint, it may appear as a knot or lump at the area of the joint. Finger lumps commonly occur at the joint area and are indicative of osteoarthritis and other arthritis-related conditions. Traumatic causes of finger lumps range from bug bites to severe injuries.
Both benign and malignant tumors of the skin, soft tissues, or bone can appear as a finger lump. In these cases, either a biopsy or surgical removal of the finger lump can determine whether cancer is present. Cysts, which are fluid-filled, sac-like structures, can form on the finger and may appear like a lump. Some cysts may be present at birth, while others develop as a result of inflammation, tumors, or wear-and-tear on your body over time. Conditions that produce inflammation throughout the body, such as rheumatoid arthritis, a chronic autoimmune disease characterized by joint inflammation, may be associated with finger lumps.
Finger lumps caused by infection, inflammation or trauma are usually temporary and subside as the underlying condition resolves. Finger lumps that persist or continue to grow over time may signal more serious conditions, such as tumors.
If you have any finger lump that is persistent or causes you concern, seek prompt medical care.
