Cancer symptoms: One sign of cancer you must never ignore, even if it only happens once
More than a third of the people in the UK will develop some form of cancer, according to the NHS. While most people are aware of some of the typical symptoms of cancer, some can be very subtle and easily overlooked. Health experts warn on taking any unexplained changes to your body seriously, even if you think they are no big deal. One symptom you must always see a doctor about, even if it only happens once, is blood in your urine.
Blood in the urine is a symptom of prostate cancer in men, as well as kidney cancer and bladder cancer.
While blood in the urine isn’t usually caused by anything serious, the NHS warns on getting it checked out by a GP.
This is the case even if it only happens once, you don’t have any other symptoms, there’s only a small amount of blood or you’re not sure it’s blood.
“Blood in urine must be checked out because it can be a sign of cancer. This is easier to treat if it’s found early,” said the NHS.
Unexplained bleeding from other parts of the body can also be a symptom of cancer.
This may include blood in the stools or vomit, or while coughing.
Blood in the stools is a symptom of bowel cancer or stomach cancer. According to the NHS, a small amount of one-off bleeding is not usually a serious problem.
However, see a doctor if you have had blood in your poo for three weeks, or if your poo has been softer, thinner or longer than normal for three weeks.
Also see a doctor if blood in the poo is accompanied by pain around the bottom, or pain or a lump in your tummy, or if you’ve lost weight for no reason or have been more tired than usual.
Call 111 urgently if your poo is black or dark red or you have blood diarrhoea for no obvious reason.
Blood in vomit can also be a sign of stomach cancer, as well as cancer of the oesophagus.
If you vomit blood, see a GP or go to A&E as soon as you can. Vomiting blood has a number of causes and it’s important to work out what the cause is.
Experiencing bleeding while coughing is a symptom of lung cancer and throat cancer.
The NHS urges coughing up blood isn’t usually a sign of a serious problem, but you should see a GP as soon as possible just in case.
This is still the case if you only cough up a few spots of specks of blood.
“These symptoms are often caused by other, non-cancerous illnesses, but it’s important to see your GP so they can investigate,” said the NHS.
