A doctor has issued a stark warning about a 'sticky' symptom that could be an indication of a dangerous cancer - stating "you shouldn't ignore this".

As most people know, cancer is a potentially fatal disease that arises when abnormal cells divide uncontrollably and spread. These rogue cells can also invade and damage nearby tissues and organs. Cancer Research UK reports that approximately 375,000 new cancer cases are diagnosed in the UK each year - that's around 1,000 every day.

The disease is responsible for 167,000 deaths annually. Therefore, being vigilant for any warning signs could be a matter of life and death. With this in mind, Doctor Jen Caudle, from the US, took to TikTok to share nine key signs of cancer, reports the Express. One such sign she highlighted was night sweats. Dr Caudle explained: "Night sweats can be due to a number of things, but we have to make sure in many, many situations that it is not cancer."

Many of us experience some form of sweating at night, particularly during the hot summer months. But consistently waking up drenched in sweat could be a red flag for cancer. The NHS advises: "Most people sweat during the night If you regularly wake up with soaking wet sheets you should get it checked by a GP.

"Night sweats are when you sweat so much that your night clothes and bedding are soaking wet, even though where you're sleeping is cool." Cancer Research UK includes "very heavy night sweats" in its list of general signs of cancer on its website However, the charity also mentions that these symptoms could be a side effect of medications or less serious illnesses. The charity states: "Sweating at night or having a high temperature (fever) can be caused by infections or a side effect of certain medications.

"It's also often experienced by women around the time of the menopause." Despite this, the charity recommends consulting your GP if you experience these symptoms. "But speak to your doctor if you have very heavy, drenching night sweats, or an unexplained fever," it advises. Dr Caudle also highlighted other cancer symptoms that should prompt a visit to the GP: If you experience any unexplained symptoms, you should consult your GP.
