13 Signs of Cancer in Men You Need to Stop Ignoring

See a doctor about these or any other unusual pains or changes.

Cancer in men

Signs of cancer in men can often appear to be minor issues or linked to other diseases or conditions. This is why men should never ignore any health symptoms. Here are some signs of cancer to look out for, according to doctors.

Difficulty urinating

If itโ€™s consistently difficult to urinate, or thereโ€™s blood in your urine or semen, or if you experience unexplained erectile dysfunction, see your doctor; these could be symptoms of prostate cancer. โ€œUnfortunately, there arenโ€™t noticeable symptoms of prostate cancer until the aggressive stages,โ€ says Moshe Shike, MD, gastroenterologist at Memorial Sloan Kettering Cancer Center in New York City. Dr. Shike says he frequently sees patients who ignore these symptoms for up to six months before they seek help, but the sooner you check out your symptoms, the better.

Testicular changes

Just as women should be familiar with how their breasts look and feel, men should pay attention to their testicles. If you notice changes in size to one or both, if they feel swollen or extra heavy, or if you feel a lump, these symptoms could indicate testicular cancer, says Maurie Markman, MD, an oncologist at Cancer Treatment Centers of America. Testicular cancer is most common in young and middle-aged men. However, note that regular self-exam is recommended against by evidence and the USPSTF.

Noticeable skin changes

Men over 50 are more likely to die from skin cancer than women in the same age group; young men have a higher probability of developing deadly melanoma (the most serious skin cancer) than any other cancer,ย  according to the Skin Cancer Foundation.ย It’s easy to miss the early warning signs of cancer in men, says Rich Wender, MD, chief cancer control officer for the American Cancer Society. โ€œMany people think freckles, moles, or a darker age spot is just like the others theyโ€™ve had,โ€ he explains. If you notice a mole getting darker, larger, or becoming raised, get it checked. With melanoma, spots are often irregularly shaped (not round), significantly darker in color, or even two distinctly different colors within one spot, he says. โ€œMelanoma is far less common than other skin cancers, but has the potential to be more deadly,โ€ says Dr. Wender. โ€œHowever, many melanomas have a long period where theyโ€™re not invasive and easy to cure, as long as theyโ€™re caught early.โ€

Sores or pain in your mouth

A cold sore that heals is probably nothing to worry about, nor is a toothache that goes away after a trip to the dentist. But if you notice sores that donโ€™t heal, pain that sticks around, white or red patches on the gums or tongue, and any swelling or numbness of the jaw, it could be a sign of some mouth cancers. Men who smoke or use chewing tobacco have an increased risk of developing mouth cancer, says Dr. Markman. โ€œMore men smoke than women. Smokers and users of chewing tobacco need to be far more concerned with sores in their mouth that do not heal quickly, compared to non-smokers,โ€ he says.

Chronic coughing

A cough that lasts three weeks or moreโ€”without other symptoms, such as a cold or allergiesโ€”could be an early symptom of lung cancer. Leukemia also can lead to bronchitis-like symptoms. โ€œIf itโ€™s different than your regular cough and if it persists, or you cough up a little blood, thatโ€™s significant,โ€ says Dr. Markman. Some lung cancer patients report chest pain that extends up into the shoulder or down the arm.

Blood in your stool

It could be hemorrhoids or something benignโ€”but it could also be a symptom of colon cancer. Routine screening typically starts at age 50, but cases are becoming more common in younger adults, which is why itโ€™s important to see a doctor for any suspicious symptoms that could turn out to be signs of cancer in men. โ€œItโ€™s easy to dismiss it as hemorrhoids or constipation, and if the problem comes and goes, people reassure themselves that nothingโ€™s wrongโ€”especially younger people,โ€ says Dr. Wender. โ€œBut blood in a bowel movement is never normal, so get it checked out.โ€

Stomach pain or nausea

Everyday digestive distress is rarely cancerโ€”but you should see a doctor if you notice persistent stomach cramps or are starting to feel nauseated all the time. It could be something as simple as an ulcer, but it could also signal leukemia or esophageal, liver, pancreatic, or colorectal cancer.

Frequent fevers or infections

If youโ€™re usually healthy but notice yourself getting sick or feverish more frequently, it could be an early sign of leukemia. This blood cancer triggers the body to produce abnormal white blood cells, which weakens the bodyโ€™s infection-fighting abilities. Be on the lookout for flu-like symptoms that donโ€™t go awayโ€”it could be one of the signs of cancer in men.

If a sore throat is nothing serious, one of these home remedies for sore throats should be all it takes to relieve the pain. However, a sore throat that persists for a few weeks and gets worse could be a symptom of throat or stomach cancer, as well as an early sign of lung cancer.

Excessive bruising

A random bruise is probably nothing to worry about. However, if you start to notice bruises popping up all the time, especially in places you wouldnโ€™t normally get them, like your hands or fingers, see a doctor. Unusual bruising can be a symptom of leukemia, according to Cancer Treatment Centers of America. Over time, leukemia impairs the bloodโ€™s ability to carry oxygen and clot.

Unexplained weight loss

โ€œWeight loss for a lot of Americans is a good thingโ€”everyoneโ€™s dietingโ€”but if you have less appetite when you usually have a good appetite, and thereโ€™s no big life event or problems happening to cause that, get it checked out,โ€ says Dr. Markman. Losing weight can be a side effect of many different cancers such as esophageal, pancreatic, liver, and colon, but itโ€™s an especially common symptom of leukemia or lymphoma, says Dr. Wender. Unexplained weight gain can signal a big problem tooโ€”it’s one of the essential medical facts doctors think you should know.

Persistent fatigue

Everyone has low-energy days. However, if you feel tired every day for more than a month, or experience shortness of breath when you didnโ€™t before, see a doctor, says Dr. Wender. Leukemia and lymphoma commonly cause persistent fatigue. โ€œMost of the time it wonโ€™t be cancer, but get it checked because you never know,โ€ he says.

Chronic headaches

If youโ€™re not prone to migraines and never get headaches, but suddenly find yourself popping pain medicine all the time, it could be a sign of a brain tumor, which causes pain by pressing on nerves.
