  • Through the circulatory (blood) system (hematogenous)
  • Through the lymphatic system.
  • Through the body wall into the abdominal and chest cavities (transcoelomic).

What causes cancer to metastasize?

Cancer metastasizes due to several factors, namely attack by the immune system, lack of oxygen and necessary nutrients, large amounts of lactic acid produced by glycolysis and increased cell death. Therefore, the majority of the presently available treatments for cancer also bear the potential to induce metastasis.

Can you feel cancer spreading?

Cancer cells that have more genetic damage (poorly differentiated) usually grow faster than cancer cells with less genetic damage (well differentiated).

Which cancer is most likely to metastasize?

Why is metastatic cancer not curable?

Rarely are the terms “cure” and “metastatic cancer” used together. That’s because cancer that has spread from where it originated in the body to other organs is responsible for most deaths from the disease.

How long can you live with Stage 4 cancer?

Stage 4 cancer usually has spread to multiple places in the body, meaning you can live only a few weeks or a few months. In rare cases, some people may survive for several months or even a year with stage 4 cancer, with or without treatment.
