It is wrong to say that cancer patients cannot eat chicken. Cancer patients can eat chicken, including chicken, egg, or hen. Some people say that cancer patients can not eat chicken, which is mainly due to some erroneous traditional concepts that such nutritious food as hen is hairy, which may cause cancer recurrence and metastasis and promote further development of tumor after tumor patients eat it, but there is no scientific basis for this statement, and a large number of relevant clinical studies have proved that eating chicken will not make cancer worse. In the past, the so-called hairy substances were mainly allergenic substances that could cause allergic diseases. This was due to the fact that in the traditional past, the ancient people were able to consume fewer kinds of proteins, which made them relatively more susceptible to allergy to certain high-protein foods, but there is no longer such a situation nowadays. Cancer patients are especially in need of high-quality protein, and chicken can effectively supplement the low protein and low vitamin situation of patients, so cancer patients can eat chicken, drink chicken soup and eat eggs.
