Oncological diseases often develop without obvious manifestations, so in the early stages go unnoticed. However, there are a number of symptoms that should alert and be a reason for the examination, even if the overall well -being seems normal.
One of the most characteristic alarm signals is the sudden weight loss without changing nutrition or lifestyle. People often perceive this as a positive phenomenon, especially if overweight was a problem. However, losing weight is not obvious is a serious reason to see a doctor, especially if it is accompanied by constant fatigue.
Another dangerous sign is the slow healing of wounds or the appearance of ulcers in the mouth that do not last for a long time. Similarly, you should pay attention to bruises that occur without injuries. Such manifestations can be symptoms of disorders in the hematopoietic system or even oncopathologies.
Prolonged abdominal pain or nausea that do not have an obvious explanation (such as poisoning or gastritis) also need attention. According to doctors, such manifestations can signal the tumors of the gastrointestinal tract or cancer of the liver or pancreas.
Another symptom that is often ignored is a cough that does not pass for three weeks. It can be a sign of not only lung cancer, but also leukemia, lymphoma, laryngeal cancer or esophagus.
Finally, unclear pain in any part of the body, which occurs regularly and has no apparent reason, should cause anxiety. If the pain lasts or increases, the examination is mandatory.
Doctors emphasize that for any unusual or prolonged symptoms, it is better to consult a doctor and undergo a diagnosis. The early stage cancer is much better treated.
