What is the mousse surgery that Biden underwent?

During mousse surgery, delicate layers of skin are removed. Each thin layer is carefully examined to detect the signs of cancer. This process continues to ensure that there are no signs of cancer. This surgery usually takes a few hours. Using a local anesthetic to anesthetize the area, which means that patients are in a state of vigilance. It is unclear whether Biden was awake during the procedure and when exactly. The goal of the “mousse process” is to eradicate the largest possible amount of cancerous skin tissue with the least possible damage to the surrounding healthy tissues. It is a gradual process where the layers of the skin are removed in stages. First, the surgeon uses a scalpel to remove the cancerous skin tissue at the surface level, knowing that there may be more cancerous tissues under the surface, as the majority of skin cancer is usually hidden under the surface. The surgeon is planning the place of extracting the cancerous tissues in the body, taking a sample of that fabric to the laboratory, dyeing it, and cutting it into sections. The technicians of specialized tissue samples place slices to examine them under a microscope. Then the doctor examines the edges of each section of the tissue to find evidence of cancer residue. And if the surgeon finds cancerous cells under a microscope, their location is located on the map. Some wounds resulting from mousse surgery are large enough to require a sunglass to close, and usually heal within two weeks. As for the smaller wounds, it may heal on their own within about a month. Patients are usually able to leave the clinic two to six hours of surgery, depending on the size of the affected area. (Russia today)
