Can cancer patients die suddenly?

Most cancer cases are diagnosed, and patients receive various therapies, including surgery and palliative care, before death. However, in most cases cancer progresses, whereas other diseases, such as circulatory disease, can cause sudden death.

How long can you live with metastatic cancer?

A patient with metastasis to the liver and lung has a median life expectancy of less than six months. A patient with widespread metastasis or with metastasis to the lymph nodes has a life expectancy of less than six weeks.

Is metastatic cancer curable?

In some situations, metastatic cancer can be cured, but most commonly, treatment does not cure the cancer. But doctors can treat it to slow its growth and reduce symptoms. It is possible to live for many months or years with certain types of cancer, even after the development of metastatic disease.

Is metastatic cancer always Stage 4?

The metastatic tumor is the same type of cancer as the primary tumor. Cancer that spreads from where it started to a distant part of the body is called metastatic cancer. For many types of cancer, it is also called stage IV (4) cancer.

How long can you live with Stage 4 metastatic cancer?

While treatable, metastatic breast cancer (MBC) cannot be cured. The five-year survival rate for stage 4 breast cancer is 22 percent; median survival is three years. Annually, the disease takes 40,000 lives.

Can chemo cure metastatic cancer?

There are many treatments for metastatic cancer. It often depends on where the cancer began and where it has spread. Chemotherapy is most commonly used, along with radiation, to shrink tumors. Memorial Sloan Kettering doctors are developing many innovative treatments for metastatic cancer.

What is the most common site of metastasis?

Metastatic tumors are very common in the late stages of cancer. The spread of metastasis may occur via the blood or the lymphatics or through both routes. The most common sites of metastases are the lungs, liver, brain, and the bones.

What stage is metastatic cancer?

Metastatic cancer is commonly called stage IV cancer or advanced cancer. It occurs when cancer cells break off from the original tumor, spread through the bloodstream or lymph vessels to another part of the body, and form new tumors. Nearby lymph nodes are the most common place for cancer to metastasize.

Why would it be more difficult to treat cancer once it has metastasized?

It could possibly be due to the basic biology of metastatic tumors and the lack of treatments that target their biology. For example, the genetic characteristics of metastatic tumors may make them highly resistant to standard treatments. Another thing is that each metastatic tumor may be growing in a different organ.

Can metastatic cancer go into remission?

While metastatic breast cancer may not go away completely, treatment may control it for a number of years. If one treatment stops working, there usually is another you can try. The cancer can be active sometimes and then go into remission at other times.

What is the most aggressive cancer?

Because pancreatic cancer progresses rapidly, and no method of early detection has been discovered, it is one of the most dangerous types of cancer. The one-year survival rate is 25 percent, and the five-year survival rate sits at only 6 percent.
