Never had any symptoms of pain. She had a mental tension over a litigation that did not go in her favor due to an alleged lapse of the legal practitioner. This was in Oct / Nov 2018 . She is a non veg. She underwent a uterus removal operation some years ago. Presently on medication. Chemotherapy or surgical operation risky according to medical practitioners advice. Could this be classified as a bacterial disease. Suggestions for diet and treatment.

    1. Cancer can have many causes- ranging from hereditary to even pathogenic. However, in this case, it seems to be a combination of several factors. There is no definitive evidence that stress leads to cancer, but many theories do exist supporting the same. One of the most popular theories is that continuous exposure to stress and associated hormones may promote growth and spread of tumours. Coming to the question, this case cannot conclusively be classified as a bacterial disease due to the involvement of several factors.

      Stage 4 stomach cancer is usually not curable, but it is certainly treatable. The primary goal is to ease the symptoms and control the spread of cancer. Furthermore, the treatment depends on the specific characteristics of the disease. Usual treatments for stage 4 stomach cancer may include radiation therapy, chemotherapy or even targeted drug therapy.
