As we all know, with the change of living environment, lifestyle and dietary structure, the incidence of cancer is increasing and it has become one of the major killers threatening human health and life, but in reality, patients and family members should still treat it correctly and actively, which undoubtedly has positive practical significance. If one person has cancer, the whole family will be upset. It is unfortunate to have breast cancer, the patient is depressed and even pessimistic and desperate, and as a family member, you have to endure the mental pain and try your best to take care of your loved ones. The nature and extent of the lesion should be clarified as early as possible through systematic and programmed combined methods (including clinician palpation, triple-operator scanning, ultrasound detection, mammography and cytopathological examination). It is worth mentioning that aspiration cytology is a very important diagnostic tool, and some patients and family members have a lot of doubts and fears about it, wrongly believing that aspiration will lead to the spread of cancer cells. In fact, this is a misconception. As far as breast cancer is concerned, medical experts at home and abroad have analyzed and studied tens of thousands of cases of various tumors by puncture, and have not found that the spread and metastasis of cancer cells are caused by puncture examination. It is because when the breast cancer lump grows to one centimeter in size, it has been more than three years, giving sufficient time for cancer cells in the blood and lymphatic system to spread and often latent in the body in the form of micro-metastases. Therefore, early diagnosis by safe and quick cytological puncture is conducive to preoperative three-cycle neoadjuvant chemotherapy after diagnosis, which can inhibit and kill cancer cells in the blood and lymphatic system and lay a good foundation for the surgical effect. Family members should actively assist medical personnel to help patients to relieve their worries and not to believe in some false propaganda. Believing in science is more realistic and reliable than hoping for a miracle. In addition, the timing of surgery should also listen to the doctor’s choice, clinical reports that premenopausal women choose early luteal surgery is better. If surgery is performed in the non-luteal phase, the immune function is suppressed during ovulation, the vitality of natural killer cells is reduced, there is no anti-estrogen secretion at this time, the estrogen level rises, the cell adhesion decreases, plus the secretion of follicular growth factor rises, all of which can promote the spread of cancer cells in the body, and if surgery is performed at this time, the metastasis of cancer cells will be accelerated. In conclusion, breast is an organ located on the surface of the body, and the chance of surgical removal of tumor is higher. However, it is scientifically proven that to complete the diagnosis and treatment according to the standard, it is often necessary for the family to help the patient to complete it in order to achieve the ideal outcome. It is worth mentioning that when patients feel frustrated, pessimistic or even desperate about their condition, family members should control their emotions in front of patients, try their best to enlighten, persuade and encourage, and can tell some examples of colleagues, friends or neighbors who are cured of cancer to help solve the knot in their minds and be able to face the reality with optimistic revolutionary spirit. Even if the patient is at an advanced stage or even at the time of death, we should assist the medical staff to take good care of the patient, so as to alleviate the patient’s pain, prolong the life, and even better finish the last part of the life.
