15 potential cancer warning signs you may overlook

Loss of hunger or rapid weight loss of 10 pounds or more for no clear reason could be signs of cancer, especially esophageal, lung, or stomach cancers.

A fever is a common sign of an infection or sickness, like the flu. A fever might not be a big deal by itself. On the other hand, you should see a doctor if you have a high fever and night sweats that won't go away for several weeks and can't be explained by an illness, or if you get illnesses all the time.

See a doctor if you have persistent pain anywhere in your body that doesn't seem to be caused by an injury or illness and doesn't get better with normal treatments.

If you don't normally have heartburn or indigestion but start getting them often and they won't go away, you should see a doctor.

Pain and soreness in the abdomen, such as bloating, a stomach that doesn't feel empty after eating, or feeling full quickly, along with nausea, could be signs of a digestive system cancer, such as liver or pancreatic cancer, or a gynecologic cancer, such as ovarian cancer in women.

Get your mouth and throat checked out if you have sores, tumours, or white patches that won't go away on your lips, tongue, gums, or anywhere else in your mouth or throat. This is especially important if you smoke or drink a lot. These signs could be signs of mouth cancer.

Make an appointment to see your doctor if you have constipation or diarrhoea that doesn't go away after a few weeks, or if you have to go to the toilet more often or in pain.

In men, swelling or lumps in these places could be signs of genitourinary cancers like prostate or testicular cancer. In women and men, they could be signs of breast cancer.
