There was a flurry of media interest earlier this week as the British papers reported on a study that says most people have little idea about the warning signs for cancer.

Thankfully, the wonderful National Health Service site NHS Choices in conjunction with Cancer Research UK clarified the situation, with a list of the 12 warning signs to look out for. If you’re suffering any of these, it’s advisable to seek advice from your doctor. Possible signs and symptoms of cancer:

• Unexplained weight loss (see information box)
• Unusual swellings or lumps anywhere on the body
• Changes in the size, shape or color of a mole
• Ulcers or sores that don’t heal
• Blood in your urine or feces
• Changes in bowel habits that last longer than six weeks
• Problems passing urine
• A cough or hoarse voice persisting for longer than three weeks
• Difficulty swallowing
• Repeated heavy night sweats
• Unexplained persistent pain lasting longer than four weeks
• For women, unusual change to the breast, or vaginal bleeding after menopause or between periods

Developing any of these symptoms does not mean that a person necessarily has cancer, but it is important to speak to a doctor if they appear.
