neoplastic alopecia
Introduction
Introduction Many tumor patients have a phenomenon of dislocation, but the cause of hair loss is not a tumor. It is the various means used by patients to treat tumors, such as radiation therapy, chemotherapy, and so on. This phenomenon is called tumor hair loss.
Cause
Cause
Radiation therapy, chemotherapy, etc. These treatments all kill cancer cells by special means. While killing cancer cells, there are still many side effects, such as tissue necrosis, gastrointestinal adverse reactions, nausea, vomiting, skin discomfort and so on. Hair loss is one of its common side effects.
The human hair follicle epithelium grows rapidly and is extremely sensitive to chemotherapy. Hair loss is common in the application of doxorubicin, methotrexate, and dactinomycin. The patient should be explained before treatment to eliminate the patient's mental stress. Ice or chemical refrigerant ice cap can be used to prevent hair loss. Wear an ice cap 5 to 10 minutes before the drug is administered, and maintain it for 30 to 40 minutes after injection to reduce the drug entering the scalp. However, malignant lymphoma and leukemia should be contraindicated to prevent meningeal metastasis.

Tumor-induced alopecia can be diagnosed due to the removal of tumors during radiotherapy or chemotherapy.
Diagnosis
Differential diagnosis
1 Hair loss caused by burns, burns, accidental injury and tissue that damages the nipple is called scarring hair loss.
2 endocrine disorders, caused by hormonal abnormalities. The function of hormones is like the lubricating oil of the machine, and the development of hair is mainly related to female hormones. In the case of deficiency, the effect of cells will be weakened and the productivity will be reduced.
3 Due to long-term mental depression or tension, the sympathetic nerves are tight, and as a result, the microvasculature leading to the nipple is atrophied, and nutrients cannot be supplied, so that the hair falls off. Round alopecia is a typical symptom.
4 When the raw material for producing keratin, that is, the amino acid is lacking, or the vitamins and minerals having a supplementary effect are insufficient, the hair cannot be regenerated normally, and the hair becomes healthy;
Another example is the loss of the original endocrine, such as prenatal, postpartum or severe illness. t is one of the reasons; however, hair loss caused by nutritional disorders still accounts for the majority.
5 The sebaceous glands in the pores, if there is excessive sebum secretion, hinder the keratosis of the hair roots and cause lipid-induced alopecia. However, if the sebum secretion f is small, the scalp and hair roots will be excessively dry, and similarly cause alopecia.
6 The side effects caused by commonly used drugs, especially antibiotics or certain chemical agents, can also cause dislocation. Inflammation caused by cold-hot chemicals, hair dyes, etc. can also cause hair loss.
7 Others, such as high fever, habitually combing hair, often stretching your hand to pull the hair, or often go to the beauty salon to dye, perm, etc., will cause hair loss. Understand these factors and improve them.
