As a student doctor, I have seen many patients who had cancers growing in their bodies and don’t feel it and don’t have any symptoms until it is too late (until the tumor has metastasized to other organs)
I have seen a patient who has lymphoma (a type of blood cancer) He didn’t feel anything; he literally had no symptoms, but one day he started to have some symptoms related to his respiratory system like cough, dyspnea, hemoptysis. When he did a chest x-ray, he was found to have massive pleural effusion (water on the lung) due to the tumor metastasized to his lung. He had an x-ray similar to that. Look at the left lung!
Not only that but he also, when he was asked to do a CT scan on his abdomen, he was found to have the tumor metastasized to his liver. (Can you see these blackish areas? These are multiple tumor masses growing at his liver)
I knew that this patient had a very bad prognosis and he most likely will pass away in a few months. It is very sad to know that. The tumor started with literally one cell, but look how bad it is. It grows and doesn’t give any sign until it is too late. This is why they are called malignant tumors; they are literally malignant! No signs no symptoms, with huge bad progression.
