Having surgery does not negate the risk. Unless you can protect yourself!

Having surgery reduces the risk, As long as you can protect yourself, you will stay healthy.

Treatments and the surgery that is a part of it are focused on treating the current disease. In order to prevent the disease from occurring again and to stay healthy, it is necessary to improve the conditions that cause the disease.
While the body is trying to protect itself and sometimes even try to treat itself, it can trigger many diseases. For example; Unless you change your nutritional conditions and change your preferences to healthy food, intestinal infections and colon cancer, which often occurs after long-term intestinal problems, may recur. It is similar in the lung. As long as you eliminate harmful habits such as living conditions and smoking that can harm the lungs, the body will not allow the same diseases to develop again.
We should see this example as the same as changing living habits to prevent the recurrence of cardiovascular diseases that occur as a result of excessive fatty and excessive animal nutrition. To protect against fatty liver that may occur as a result of irregular nutrition or alcohol consumption, chronic liver disease that may develop subsequently, liver cirrhosis and liver cancer that may develop, it is also necessary to change habits.
In tongue-lip and larynx cancers that develop due to harmful habits such as malnutrition and smoking, and in skin cancers that occur due to excessive exposure to sunlight, changing habits, avoiding the sun, eating right and healthy, stress control, developing good and quality sleep, preventing harmful effects on the body, Eliminating habits will reduce the chance of recurrence of diseases.
Today, we realize that many diseases, such as cervical cancer caused by microbial diseases (HPV), iodine deficiency caused by irregular nutrition, and diseases that can lead to thyroid cancer due to autoimmune reactions, are based on misuse of life. Now, while treating diseases, we want our patients to be a part of the treatment by regulating their own lifestyles. To summarize briefly, although lung cancer can develop normally, it is 20 times more common in smokers. Colon cancer has increased nowadays due to increased consumption of animal foods. 
When we consider cancers related to lifestyle and consumption habits in this way, we see bladder cancer, where heavy consumption of caffeine and cigarettes are considered risk factors, ovarian, prostate and breast cancers, which are observed to increase due to excessive use of proteins, and stomach cancer, which occurs due to excessive stress and irregular nutrition. When diseases such as these are considered, no matter what treatment protocol is applied, changes in the patient's lifestyle and habits can change the quality of life and the treatable capacity of the cancer for the better. In fact, all bad habits (overeating, obsessions, eating disorders, harmful substance use habits) emerge as a result of the stresses experienced by the person. 
When a person encounters stress that he cannot control and especially when he feels a lack of love, he feels helplessness and anger. Those who prefer to fight are fight or flight, the two basic responses of the brain to the perception of threat at the time of stress. When they cannot leave the conditions they are in, they may try to escape from the environment with the diseases they develop as a part of their defense mechanism.
No one expects or wants much from an unhealthy body or an unhealthy person, so when people are sick, the environment does not change, but they become isolated from the environment due to the disease. Although the diseases that are often called psychosomatic (disease caused by excessive stress and psychological structure in the body) are sometimes mild, if the person's stress condition lasts for a long time, these diseases, which are initially seen as harmless, can turn into permanent and even life-threatening diseases such as cancer. That is why we say this. So, change your habits, yourself, stay healthy.
