13 signs of cancer men are likely to ignore

If it’s consistently difficult to urinate, or there’s blood in your urine or semen, or if you experience unexplained erectile dysfunction, see your doctor; these could be symptoms of prostate cancer. “Unfortunately, there aren’t noticeable symptoms of prostate cancer until the aggressive stages,” says gastroenterologist Dr Moshe Shike. 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.

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 Dr Maurie Markman, an oncologist. Testicular cancer is most common in young and middle-aged men.

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, according to the Skin Cancer Foundation. It’s easy to miss the early warning signs of cancer in men, says Dr Richard Wender, a cancer specialist. “Many people think freckles, moles, or a darker age spot is just like the others they’ve had,” 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 colour, or even two distinctly different colours within one spot, he says. “Melanoma is far less common than other skin cancers, but has the potential to be more deadly,” says Dr Wender. “However, many melanomas have a long period where they’re not invasive and easy to cure, as long as they’re caught early.”

Here are the skin changes you should never ignore.

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 don’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. “More 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,” he says.

Here’s what your tongue can reveal about your health.

A cough that lasts three weeks or more – without other symptoms, such as a cold or allergies – could be an early symptom of lung cancer. Leukaemia can also lead to bronchitis-like symptoms. “If it’s different than your regular cough and if it persists, or you cough up a little blood, that’s significant,” says Dr Markman. Some lung cancer patients report chest pain that extends up into the shoulder or down the arm.

It could be haemorrhoids or something benign – 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 it’s important to see a doctor for any suspicious symptoms. “It’s easy to dismiss it as haemorrhoids or constipation, and if the problem comes and goes, people reassure themselves that nothing’s wrong, especially younger people,” says Dr Wender. “But blood in a bowel movement is never normal, so get it checked out.”

Everyday digestive distress is rarely cancer ­– 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 leukaemia or oesophageal, liver, pancreatic, or colorectal cancer.

If you’re usually healthy but notice yourself getting sick or feverish more frequently, it could be an early sign of leukaemia. This blood cancer triggers the body to produce abnormal white blood cells, which weakens the body’s infection-fighting abilities. Be on the lookout for flu-like symptoms that don’t go away.

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.

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 wouldn’t normally get them, like your hands or fingers, see a doctor. Unusual bruising can be a symptom of leukaemia, according to Cancer Treatment Centers of America. Over time, leukaemia impairs the blood’s ability to carry oxygen and clot.

Here are more sneaky reasons you’re bruising easily.
