For cancer patients and their family members, rational perception of cancer is more relevant than treatment. After cancer diagnosis, making a rational post-cancer recovery and life plan is not only about how patients can spend a quality post-cancer life, but also about the life and happiness of family members. The final diagnosis of cancer needs to rely on pathological diagnosis. Cancer is not something that happens in a year or two, so there is no need to rush to get the diagnosis report in a day or two. To ensure the quality of pathological diagnosis, it is necessary to give the pathologist enough time to examine the patient comfortably. For patients and their family members, it is hard to avoid the shock and panic when they first get the pathology diagnosis report, and it is understandable that they cannot understand and accept the fact that they have cancer for a while, and they struggle with why they or their family members are the ones who have cancer. However, over-questioning the doctor’s diagnosis, repeatedly consulting multiple hospitals and adopting the mentality of “comparing three different hospitals” to see a doctor may not necessarily lead to better results. At present, there are many cancer treatment methods. However, any problem that needs to be solved by multiple methods means that there is a lack of effective methods. This is the case with cancer treatment. Although, not all cancers require surgery, a single treatment often does not cure cancer and generally requires a combination of approaches, and it is important to develop a comprehensive combination treatment plan. In addition, overdiagnosis and overtreatment determination due to multiple factors is common. The “reluctance” of cancer patients and their families is an important reason for this. The prognosis or survival of cancer is closely related to the stage of cancer. Although, with the development of early diagnosis and early treatment methods, the prognosis of stage I and II cancers has been greatly improved. However, the prognosis of stage III and IV cancers is still very poor. Patients and family members should adjust their mindset as early as possible, accept the outcome of cancer rationally, and maintain a peaceful state of mind to actively cooperate with treatment. 3. “Goodwill concealment” does not help to improve the condition It is indeed unfortunate to have cancer, and it is inevitable that patients and their families will have short term emotional fluctuations. However, the goodwill concealment of patients by their family members will not help to improve the disease, and may not be good or even have the opposite effect. Therefore, it may be more meaningful for patients to understand their physical condition in time, to help them get through the emotional fluctuation period as soon as possible, to formulate a financial budget for cancer treatment and an appropriate comprehensive treatment plan that matches the family’s financial status, to plan a lifestyle with cancer that follows the patient’s wishes, and to spend the rest of their lives peacefully after cancer. In conclusion, a rational view of life and early planning of a cancer treatment and rehabilitation plan that is appropriate to the patient’s and his family’s situation are the fundamentals of positive cancer treatment.
