Precancer is a condition in which cells appear abnormal and have a high risk of developing into cancer. Experts also note that not all cases of precancer develop into cancer, according to the health website Healthline (USA).
Persistent diarrhea with blood in the stool, weight loss and fever may be a sign of cancer.
Precancerous conditions are usually detected through screening and regular health check-ups. Blood tests are almost mandatory. In addition, many cases of cancer are also detected when the body has certain symptoms or health problems.
Signs of precancer that patients can detect early include:
Persistent blisters in mouth
Persistent blisters in the mouth that won't go away are not a good sign, experts warn. In rare cases, these blisters can be a sign of cancer.
Nodular melanoma is a type of skin cancer that appears as a hard, raised lump that looks like a blood blister. Blisters or sores on the lips that don’t go away can also be a symptom of lip cancer. Other symptoms include a painful, bleeding lump and jaw pain.
White patches on tongue
One of the warning signs of tongue cancer is the appearance of white patches on the tongue. However, some common diseases can also have white patches that are similar. To distinguish, white patches caused by cancer will not go away no matter how many ways the patient tries.
Persistent diarrhea
Diarrhea is a condition in which a person has loose stools 6 or more times a day, continuously for at least 2 days. Prolonged diarrhea can be a sign of several types of cancer, from neuroendocrine tumors, colon cancer, lymphoma, medullary thyroid cancer to pancreatic cancer.
In addition to diarrhea, patients will also experience symptoms such as blood in the stool or rectum, weight loss, fever above 38 degrees Celsius, abdominal pain, loss of bowel control and dizziness, according to Healthline .
