Cancer is not a contagious disease, even if you share utensils with cancer patients, you will not catch cancer or anything like that, but sharing utensils may be an unhygienic habit. Generally speaking, there are some diseases that are transmitted through the oral cavity and diet, such as hepatitis A, which can be transmitted through sharing utensils. For example, if cancer is accompanied by hepatitis A, it is recommended not to share utensils and to use individual utensils separately. In addition, we need to give more care to cancer patients and do not worry that cancer will be transmitted to ourselves. Cancer patients are generally in poor physical condition and may have high consumption, anemia, hypoproteinemia and so on. In terms of diet, we should also pay attention to eating less and more meals and appropriately supplement high protein diet. Also, the psychological care of cancer patients is very important, they need the support of family and friends, more enlightenment and don’t dislike them.
