I suggest you at least go to the hospital for a B-ultrasound or CT, and check the tumor markers, at least make a diagnosis first. Didn't you say that Chinese medicine has different opinions? The second is to determine the size of the tumor. This is very important for the choice of treatment methods.
Listen to your symptoms, low back pain, I don't know if it has metastasized to the bone. If so, I'm afraid I can only accept the reality. From the point of view of pure medicine, there is no rule of law transferred to bones. If it is advanced, it is still recommended not to operate and not to intervene. It is meaningless and will only increase the physical pain of patients. If the disease is found early, we can expect a miracle. In the later stage, traditional Chinese medicine is generally used for aftercare, and there is no room for treatment.
Besides, I don't know what the Chinese medicine prescribed by barefoot doctors is at first. We can talk alone if there is an opportunity. This folk prescription is hard to say, and sometimes it will encounter miracles.
At present, it is suggested that the patient should not know the condition, strengthen nutrition as much as possible, and keep him happy and optimistic, which really helps to prolong the survival period. Patients will be more agitated in the later stage, and the emotions of their families are very important. Be patient and tolerant.
Finally, I wish your father good health!
