There is no one particular treatment for cancer but only a combination of different treatments and therapies to address the cancerous tissue. Each specific treatment depends on the requirements of the individual like his health status, age, and genetics. The different types of treatments available for the patients are followed below.
Surgery is described as the oldest treatment for cancer. Before and if the cancerous tissue has not metastasized yet, the chance of completely clearing the patient from cancer is high. Surgery involves surgically removing the abnormal cell growth affected areas entirely from the body. It is however impossible to remove the cancerous cells entirely. It is a mere means of controlling symptoms.
Also known by the name radiotherapy, this treatment involves channelizing high energy rays targeted on cancer cells. These rays target the molecules of these cells making them destroy themselves by suicide. The high energy gamma rays are produced from metals such as radium. Early radiation treatments had severe side effects like damage to healthy tissues. With innovation in technology, such adverse side effects have been adequately addressed.
Chemotherapy is often used when cancer has metastasized. It involves utilizing chemicals that interfere with the cell division process which in turn damages the protein and DNA so that the cancer cells will commit suicide and destroy themselves. This treatment is done in cycles giving the body sufficient time to heal before each session. Hair loss, vomiting, fatigue are among the common side effects.
This is a relatively new treatment that has considerable success rates. This treatment aims at fighting the tumors in the body by strengthening the immune system of the body. Systematic immunotherapy involves treating the whole body by administering an agent called protein interferon alpha that can reduce and shrink tumors.
Cancers can be linked to certain types of hormones. Breast cancer and prostate cancer are the primary examples of these cases. Hormone therapy focuses on altering hormone production in the body in such a manner that these cancerous cells stop growing and eventually kill themselves. Breast cancer therapy involves reducing estrogen levels in the body while prostate cancer consists in reducing testosterone levels by infusing certain drugs to lower them.
This treatment is very young in the medical field and has yet to have proven its theory into practicality. This is innovative and remarkable treatment involves replacing damaged genes with working ones to address the cause of cancer, damage to DNA. Researchers are trying to replace the damaged gene that issues signals cells to stop dividing with a copy of a working gene.
