Cancer cells in your bowels can spread to other organs in the body, including the liver, lungs and abdomen (peritoneal cavity). This is referred to as secondary , advanced or metastatic bowel cancer. This could be determined at the time of diagnosis or from pathology results that are performed during surgery. Also, the cancer could return after initial treatment.
Once cancer has spread to other parts of the body, it could prove extremely difficult to cure but for some this is possible. Nonetheless, with treatment, it can be controlled for some time depending on the individual.
Chemotherapy is a treatment used to deflate cancer cells and to manage their symptoms. This process is carried out by injecting the veins or ingesting tablets. The first treatment (1st line treatment) is not guaranteed to control your symptoms. In the case that it is not successful, an alternative type of chemotherapy (2nd line or 3rd line treatment) may be proposed. According to Cancer research UK, a research review found there was good evidence that chemotherapy helped people with advanced bowel cancer to live longer. Radiotherapy is another treatment that may be used to shrink cancer cells. This process is conducted by using radiation from a machine to eliminate cancer cells. The machine shatters DNA found within the cancer cells. Once the DNA is damaged, the cancer cells are either destroyed or prevented from developing further.
Other treatments that are available are SIRT and DEBTACE for liver metastases, ABLATION this is for lung and liver. Other options available is to have surgical resection which may provide a cure.
