For patients who are not suffering from cancer, bird’s nest will not accelerate the production and growth of cancer cells. In clinical practice, bird’s nest is a good tonic, which can tonic the body, while the generation of cancer cells takes place every day, but the human body can kill the prematurely generated cancer cells through its own immune system and immune mechanism to maintain the health of the body, which is a normal phenomenon in clinical practice. However, for patients who are already suffering from malignant tumors, especially those with advanced cancer, they should not eat overly nutritious food, so that most of the food will not be taken by cancer cells, which will lead to faster division and growth of cancer cells. Bird’s nest is also a very nutritious food, but taking it orally in the late stage of cancer will also lead to excessive nutrition of the human body, which will encourage the cancer cells to grow and expand too fast, so that the disease will be aggravated.
