Changes to your body's normal processes don't necessarily need to be a red flag - but it's important to know that it can sometimes be an early sign of cancer. Cancer is a condition where cells in a specific part of the body grow and reproduce uncontrollably - and it can sometimes spread to other areas. One in two people will develop some form of cancer during their lifetime, and it's crucial people be aware of the symptoms to look out for, as early detection could mean a better chance of survival. While one of the most commonly known symptoms of cancer is a lump that suddenly appears of the body, there are also more lesser-known signs we should be aware of. One of these cancer symptoms can be spotted while you're eating dinner - so it's important to be aware. Four symptoms of dementia that can appear in your eyes long before memory loss Doctors have warned that persistent indigestion or heartburn , an uncomfortable feeling in the chest caused by stomach acid travelling upwards towards the throat, could be a sign of oesophageal cancer or stomach cancer. It's important to remember that lots of people get heartburn from time to time, and it can be made worse by certain things, such as specific foods or drink, smoking or pregnancy . However, if it's persistent, it's important to get it checked by a doctor to make sure there aren't any more sinister causes. Dr Alexandra Oliver, associate clinical director at Bupa Health Clinics, told The Independent : "Occasional acid reflux can be normal, but when it doesn't go away, it can result from gastroesophageal reflux disease, a hiatus hernia, oesophageal cancer or stomach cancer." Another cancer symptom which could arise while you're eating dinner is bloating, which also isn't usually something serious, and could be caused by another gastrointestinal condition such as irritable bowel syndrome (IBS). However, if you've been bloated for most days over a few weeks, Dr Oliver advised you should speak to a doctor. GP and author Dr Anisha Patel explained that something like ovarian cancer could cause a swollen stomach. If this isn't something that's 'normal' to you, it's especially important to get it checked out. In rare cases, bloating can also be caused by other cancers such as bowel, stomach, pancreas and uterine cancer. Again, if you have any worries, or are experiencing any health issues that aren't 'normal' to you, speak to a GP. Do you have a story to share?
