After surgery for prostate cancer patients, it is definitely a good idea to pay attention to low-fat intake first. If the daily diet with high fat content exceeds the standard for a long time, it will stimulate the recurrence of prostate tumor. Do not carry on a high-calorie, high-fat diet as you did in the past, and supplement with more fresh fruits and vegetables. Meat can eat some aquatic products, and also soy products, which are fine. Vitamin A, vitamin C, vitamin E, and also vitamin D all help to reduce the risk of prostate cancer tumors. In addition, it is important to do maintenance treatment to prevent recurrence. For maintenance treatment, diet is also an important part of the whole treatment and recovery. First of all, it is definitely necessary to develop good living habits, to quit smoking and drinking, to maintain a clean and tidy environment in life, and to avoid exposure to strong carcinogens like cigarettes, which is a cliché.
