The occurrence of this disease mostly means that the body is in a state of serious dysfunction. Early symptoms: manifested as extreme emaciation, malnutrition, anemia, fatigue, inability to take care of oneself and extreme pain, mostly seen in tumor patients, so it is also known as malignant stroma of tumor. Generally speaking, after the appearance of malignant stroma, it means that the tumor has already come to a very late period, which can be said to be close to death. Causes: There are two main reasons for malignant stroma, on one hand, it is due to the overgrowth of the tumor, the normal cells of the body are occupied by the tumor cells, the tumor cells absorb the nutrients, while the normal body does not have so many nutrients to be absorbed, so it results in the exhaustion; on the other hand, it is because of the pain of the patients in the late stage of the tumor, and the malnutrition caused by the inability to eat, which can also aggravate the occurrence of the development of malignant stroma. Patients with malignant disease should pay attention to improve the body’s ability to resist disease, pay attention to balanced nutrition, eat more high-protein food, strengthen exercise appropriately, improve the body’s immunity, maintain a positive and optimistic mindset, and actively cooperate with the doctor’s treatment.
