Advanced kidney cancer mainly refers to the invasion of local surrounding tissues or systemic metastasis of the malignant tumor in the kidney, the patient’s body function is severely reduced and multiple organs are failing, so patients with advanced kidney cancer will not live for a long time objectively. However, this time cannot be quantified. Some patients may have miracles after active treatment, and their survival time may reach more than three years, but if they do not receive treatment, their survival time may only be about 1-3 months. In the early stage of kidney cancer, most patients’ lesions are confined to the kidney and do not spread, but in the late stage, due to the continuous growth and development of cancer cells, there will be a large area of spread, which will cause systemic diseases such as bone metastasis, liver metastasis and lung metastasis. Therefore, objectively speaking, if patients with advanced kidney cancer are not treated with drug intervention, their survival time is about several months, but of course, how long they can live has a lot to do with their physical condition, psychological factors and post-operative health care. Of course, how long patients can live depends on their physical condition, psychological factors and post-operative health care. Those with better physical condition and psychological factors can live longer, and family care and encouragement are also very important. Once a kidney cancer patient enters the advanced stage, try to meet all the wishes of the patient and encourage the patient more actively. No matter how long they can live, they should be strong enough to face it and try to let them spend every day happily.
