Yes, a prolonged armpit lump may be an indication of Kaposi sarcoma or cancer. Kaposi sarcoma is a type of skin cancer caused by the herpes virus and can commonly occur in the form of an armpit lump. It typically appears as dark purple bumps that may start off small but can become larger over time.
Cancerous lumps in the armpit are most likely to be lymphomas or metastatic cancers (cancer that has spread from another part of the body). A physician should confirm if the armpit lump is indeed indicative of either disease after performing some tests such as x-rays, ultrasounds, biopsies, and/or CT scans. Early detection is key when it comes to treatment for any type of cancer. If you have a persistent armpit lump that has been present for more than two weeks without any resolution, it's important to consult with your doctor immediately so they can properly diagnose and treat it if necessary.
