Penile cancer often begins as a lump or growth on the penis, typically on the glans (head) or foreskin. This growth may be small, painless, and appear as a wart-like lesion or ulcer. As the cancer progresses, the tumor can cause changes in the skin of the penis, such as thickening, discoloration, or the development of a reddish, scaly patch.

Patients may also notice an unusual discharge from the penis, often with an unpleasant odor. In advanced stages, pain or swelling in the penis, especially during urination or sexual activity, can occur. If the cancer spreads, it may cause swelling in the groin or enlarged lymph nodes.

Early-stage penile cancer is treatable, making it essential to seek medical attention if any of these symptoms occur. Regular self-examinations and prompt diagnosis play a vital role in managing the disease effectively.
