All penises look and feel different. Some are short, some are long, some are thick and some are bendy. All characteristics are normal and in most cases are not in any way dangerous, it’s just what makes them unique. But there are some penis lumps and bumps that shouldn’t be ignored.
Penile lumps are often seen on the outside of the penis and can appear as a red, raw lump or simply as just a seemingly harmless growth. Other lumps can be found under the surface by massaging the tissue, the size ranging from that of a pea to that of a golf ball.
Many penile lumps are harmless and require little treatment, others, however, can be a sign of something more serious.
Here’s five types of penis lumps that might sound like a lump on your man’s stump and worth a trip to the GP.
A Penis Cyst
A penis cyst occurs when the sebaceous glands (the ones that produce oil) on the scrotum or penis become blocked and enlarged. This leads to a firm, ball-like lump that can resemble an ingrown hair. Cysts may be smooth or slightly raised, and although they can sometimes feel worrying, they are almost always harmless.
Most penis cysts do not require treatment and often go away on their own. Attempting to squeeze or pop them usually makes the problem worse, as the cyst will often refill with fluid or pus and become red, sore, and inflamed. In some cases, surgical removal by a doctor may be recommended if the cyst grows excessively, becomes painful, or shows signs of infection.
Recommendation: Most penis cysts are harmless and nothing to worry about, but if the lump changes, becomes painful, or causes concern, it’s best to have it checked by a doctor for peace of mind.
Penile Papules
Penile papules are small, raised bumps that appear on the surface of the skin. A common type, known as Pearly Penile Papules, typically forms in neat rows around the head of the penis. They are smooth, dome-shaped, and often mistaken for genital warts. Unlike warts, however, pearly papules are not infectious, not caused by sexual activity, and require no treatment.
Other types of papules can be linked to skin conditions such as psoriasis, or in some cases, sexually transmitted infections like genital warts. This is why it can sometimes be difficult to tell the difference without professional advice.
Recommendation: Penile papules are usually harmless, but because some lumps may look similar to STIs, it’s always sensible to have them checked by a doctor if you’re unsure.
Penis Ulcers
Ulcers on the penis are more serious and should never be ignored. They usually appear as painful, crater-like sores in the skin, sometimes filled with pus or clear fluid. Unlike cysts or papules, ulcers are often a sign of an underlying condition.
Causes can include sexually transmitted infections such as herpes or syphilis, inflammatory conditions, or even, in rare cases, penile cancer. Ulcers may spread, become increasingly painful, or cause systemic symptoms like fever. Because of the wide range of possible causes, ulcers always require prompt medical evaluation.
Recommendation: A penis ulcer is never normal and should be assessed by a doctor as soon as possible to rule out infection or more serious conditions.
Plaques
Plaques are raised, thickened areas on the penis that are generally larger than one centimetre in diameter. They may feel firm to the touch and can appear on the shaft or head of the penis. Common causes include inflammatory skin conditions such as eczema or balanitis (inflammation of the head of the penis).
While many plaques are benign, in some cases they may develop due to Peyronie’s disease (a condition that causes curvature of the penis) or, more rarely, be associated with penile cancer. Because of this, persistent plaques should always be monitored and investigated if they do not go away.
Recommendation: Most plaques are caused by skin irritation or inflammation, but if they persist, grow, or cause discomfort, it’s best to see a doctor to rule out anything more serious.
Genital Warts
Genital warts are caused by the Human Papilloma Virus (HPV) and are one of the most common sexually transmitted infections worldwide. They often appear as small, fleshy lumps or clusters on the penis and can spread quickly through skin-to-skin contact. Unlike cysts or papules, warts are contagious, which makes early treatment and disclosure to partners very important.
Genital warts are usually painless but can sometimes itch, bleed, or become irritated. Treatments include prescription creams, freezing with liquid nitrogen, or minor surgical procedures. However, while these treatments remove visible warts, the virus remains in the body, and warts may return over time.
Recommendation: Genital warts are not usually dangerous but are contagious, so it’s important to seek medical treatment and talk to a doctor about management and prevention.
Not every lump or bump on the penis is a cause for alarm. Many are harmless, such as cysts or papules, and require little to no treatment. However, some – like ulcers, persistent plaques, or genital warts, can signal more serious conditions or infections.
The best approach is simple: don’t panic, don’t self-diagnose, and don’t delay if something feels unusual. When in doubt, a quick check with your GP can provide reassurance or help you get the right treatment early.
