There are many well-known cancer symptoms to be aware of – yet some are far less obvious, including a little-known sign you might notice at meal times.
Detecting cancer early is vital – and with more than 200 different types, this can prove challenging at times.
Discovering a lump, changes to a mole, abnormal bleeding or weight loss are frequently cited as reasons to visit your GP.
Cancer Research UK has put together a list of seven potential indicators that rarely receive the attention they deserve.
The most crucial thing to bear in mind is that any such symptoms are usually nothing serious – but getting them checked out remains absolutely essential.

Dr Julie Sharp, head of health and patient information at CRUK, told the Independent: “There are more than 200 types of cancer, with lots of possible symptoms.
“It’s impossible to know them all, which is why it’s important to seek your doctor’s advice.
“Catching cancer early means treatment is more likely to be successful,” she added.
“If you notice unusual or persistent changes to your health, make an appointment with your GP as soon as possible.”

Dr Alexandra Oliver, associate clinical director at Bupa Health Clinics, said there are “many” medical conditions that can cause fatigue, including cancer.
If you find yourself feeling “constantly” exhausted, to the point where it prevents you from working or carrying out your daily routine, you should inform your GP.
Women who are menstruating or going through the menopause frequently experience night sweats.
However, certain cancers can present with this same symptom, including leukaemia and liver cancer. Frequent heavy night sweats warrant a visit to your GP.
Persistent indigestion and heartburn
Indigestion and heartburn are widespread complaints stemming from particular foods, as well as affecting those who are overweight, smokers or pregnant.
Acid reflux is commonplace, but when it becomes persistent it can develop into gastroesophageal reflux disease, a hiatus hernia, oesophageal cancer or stomach cancer.
Long-lasting mouth ulcers
Mouth ulcers can arise from a variety of causes, including infections, damage from brushing or wisdom teeth complications.

However, a mouth ulcer that fails to heal within three weeks could be an indicator of mouth cancer.
Hoarseness is typically associated with a dry or sore throat and can also develop from excessive talking over a brief period.
It originates from inflammation, but should the symptom persist for more than 10 days it could signal laryngeal cancer.

Bloating is rarely anything serious and may be caused by a gastrointestinal condition, such as irritable bowel syndrome (IBS).
However, should the symptom continue for several weeks, it could be connected to gynaecological or bowel cancer.
Coughs generally clear up on their own and may also be associated with heartburn and allergies.
Should one persist for more than three weeks, it may indicate a small chance of lung cancer.
