Unexplained fever, weight loss, loss of appetite and other abnormal symptoms may appear before getting cancer.
1. Unexplained fever: Before the onset of cancer, some abnormal changes will often occur in the body, and the patient may have recurrent fever symptoms, usually low fever, which may be a typical precursor of cancer.
2. Weight loss: after cancer cells appear in the body, they may consume the nutrients of the body, and in the early stage of cancer, some patients may have continuous weight loss.
3. Loss of appetite: Cancer cells may secrete and produce some toxins and hormones, which often affect the function of the digestive system and lead to symptoms of loss of appetite.
If the above abnormal symptoms occur, it is necessary to be alert to whether they are caused by cancer, and one can promptly consult doctors for carcinoembryonic antigen, magnetic resonance imaging and other auxiliary examinations to find out the lesions, and carry out effective treatments at an early stage in order to have a better prognosis.
