Answer 1

proof that this statement is right .

Cancers that have metastasized (spread to other parts of the body) are fatal. ....Metastatic cancers have spread from where they started to other parts of the body. Cancers that have spread are often thought of as advanced when they can’t be cured or controlled with treatment. Not all metastatic cancers are advanced cancers. Some cancers, such as testicular cancer, can spread to other parts of the body and still be very curable.

As advanced cancer grows, it can cause symptoms. These symptoms can almost always be managed with treatment, even when the cancer itself no longer responds to treatment.

What is metastatic cancer?

Metastatic cancer is a cancer that has spread from the part of the body where it started (the primary site) to other parts of the body. When cancer cells break away from a tumor, they can travel to other parts of the body through the bloodstream or the lymph system. (Lymph vessels are much like blood vessels, except they carry a clear fluid and immune system cells.) Cancer cells must go through several steps to spread to new parts of the body:

• They must find ways to break away from the original tumor and enter the bloodstream or lymph system.
• They need to attach to the wall of a blood or lymph vessel and move into a new body part.
• They need to find ways to grow and thrive in their new location.
• They must be able to avoid attacks from the body’s immune system.

When cancer spreads to a new area, it’s still named after the part of the body where it started. For instance, breast cancer that has spread to the lungs is called “metastatic breast cancer to the lungs” – it’s not lung cancer. Treatment is also based on where the cancer started. If prostate cancer spreads to the bones, it’s still prostate cancer (not bone cancer), and the doctor will choose treatments that have been shown to help against metastatic prostate cancer. Likewise, colon cancer that has spread to the liver is treated as metastatic colon cancer, not liver cancer.
