In the UK, the four most common types of cancer are breast cancer, bowel cancer, lung cancer and prostate cancer. But there are over 200 types of the disease all in all, each of which have different symptoms. Most people are familiar with some cancer symptoms, such as growth in a mole or a lump in your breast, but many of the other symptoms are much less obvious. The following three symptoms are common problems which in most cases would not be a cause for concern. But in some cases, if they persist, they could be a sign of cancer.
Croaky or hoarse voice
A croaky voice is usually nothing to worry about, and often happens when you have a cold, cough or sore throat.
But if you have a croaky or hoarse voice that doesn’t go away, it could be a sign of cancers including lung cancer and cancer of the larynx.
“Having a croaky voice or feeling hoarse can be common with colds,” said Cancer Research.
“But a croaky voice that hasn’t gone away on its own should be checked out by your doctor.”
Mouth ulcers are a common problem for many people, are rarely serious and usually clear up on their own within a week or two.
But if they are long-lasting, particularly if they last longer than three weeks, they could be a sign of mouth cancer.
“It’s common to get ulcers in the mouth when you’re a bit run down. The lining of the mouth renews itself every two weeks or so, which is why ulcers usually heal within this time,” said Cancer Research.
“But an ulcer that doesn’t heal after three weeks should be reported to your doctor or dentist.”
Sweating at night is normal if the temperature in your bedroom is too hot or your bedding is making you too warm.
It can also be caused by an infection and is a relatively common side effect of medication, while women often experience night sweats during the menopause.
However, in some cases, “very heavy, drenching” night sweats can be a sign of cancer, warns Cancer Research.
Cancers commonly associated with excessive sweating include lymphoma, leukaemia, bone cancer and liver cancer.
The NHS advises seeing a GP if you have night sweats regularly that wake you up.
The health body also advises seeking medical attention if you notice any other unexplained changes to your body.
