Men are more at risk of developing and dying of cancer than women, so it’s important to keep a close eye on your body and health to monitor for symptoms, especially as you get older. Cancer becomes more and more likely as the body’s defense mechanisms slowly break down with age.
Cancer is a disease caused when cells in the body start to grow out of control. Genetic changes, or mutations, often remove the brakes that usually hold cells back from growing too quickly or stop directing cells to die off. Without these breaks and instructions, the cells act differently, and form large masses called tumors that may impact a tissue’s normal function.
Early detection is essential, as cancers found while still small are easier to treat and more likely to be survivable. There are several organs in the reproductive system of people born male that may become cancerous and cause specific symptoms.
The prostate is a walnut-sized gland in the pelvis that makes some of the components of semen. It typically grows larger with age, and tumors are common. More than half of men develop prostate cancer by age 80. In 2024, doctors will diagnose an estimated 299,010 cases of prostate cancer according to the American Cancer Society, and the disease has a five-year survival rate of 98 percent.
These tumors are common, and often don’t pose a threat, since they tend to be slow-growing. Various prostate conditions that aren’t cancerous, such as benign prostate hyperplasia (an enlarged prostate) may cause similar symptoms, so it’s essential for a doctor to review any signs immediately after they start. It's important to be screened for prostate cancer before symptoms develop, since the disease is typically easier to treat in its earliest stages.
Symptoms: Changes during ejaculation
Symptoms: Changes in the lower extremities
Symptoms (advanced stage): Changes in urination
The testicles, or testes, are the organs that make sperm and hormones. Men are usually born with two testes, located in a sac of skin behind the penis called the scrotum. Testicular cancer is the most common cancer in men between age 20 and 35, but it’s relatively uncommon. About 9,760 cases are expected to be diagnosed in 2024 and the five-year survival rate is 95 percent, according to the American Cancer Society.
Symptoms:
The penis is the external male genitalia and is also a part of the urinary system. Cancer of the penis is rare. Doctors diagnose about 2,100 cases each year, according to the American Cancer Society (ACS). The five-year survival rate is about 65 percent.
Symptoms: Changes in the penis
While men don’t naturally have large breasts, they have some glandular tissue around the nipple and chest that may become cancerous. Still male breast cancer is very rare. The ACS estimates that 2,790 cases of invasive breast cancer will be diagnosed in men in 2024. When it comes to the survival rate, about 83 percent of male breast cancer patients are alive five years after diagnosis.
Symptoms: Changes in the breast/chest
Other than cancers of the reproductive system, a few others are more common in men than women, including lung cancer, colorectal cancers, oral cancers and skin cancers. The increased incidence of these cancers may be due to hormonal or genetic differences between men and women. Still, some of these are due to different social expectations and behavioral characteristics—like being less likely to wear UV protection or more likely to work outside in the sun for long periods.
Below are some additional symptoms to monitor and discuss with your doctor:
Most of these symptoms may be normal parts of life from time to time, so don’t be too alarmed if you experience them. However, that doesn’t mean you shouldn’t speak with your doctor. The older you are, the more critical it is to pay attention to your body’s signs and signals.

While you can’t control how quickly you get older, you may be able to do some things to help detect problems early and reduce the risk of cancer:
