Breakthrough in the Treatment of Cancer
The treatment of cancer is done through very many ways. These ways depend on the type of cancer and its advancements in the body of a patient. The type of treatment also varies among people since some only receive one treatment while others require a combination of treatments such as surgery which involves radiation and chemotherapy. Other types of cancer treatment are immunotherapy, hormone therapy and targeted therapy. Cancer treatment involves clinical trials which entail teaching people about the types of cancer treatment and how they work. Below is a comprehensive explanation of the various cancer treatment.
Cancer treatment through surgery involves the removal of all or part of the infected body part using an operation. The use of surgery can be used to treat prostate and breast cancer. The treatment of prostate cancer is done through radical prostatectomy which is the main type of surgery. It involves the removal of the entire prostate gland, seminal vesicles and tissues around it.
The treatment type for breast cancer depends on the size of cancer and the area it is in the breast. This leads to the two types of breast surgery which are breast-conserving surgery and mastectomy. Breast-conserving surgery involves the removal of cancer plus the normal breast tissue bordering the infected area. Mastectomy involves the removal of the entire breast tissue.
Radiotherapy is widely used in the treatment of cancer. half of all cancer patients are treated have undergone radiotherapy. Radiotherapy basically involves the use of high-energy atomic particle waves to damage the DNA of a cell to an extent of disabling its ability to repair itself. The most common type of radiotherapy is an external-beam radiation therapy which implies that radiation comes from outside the body. Other types of therapy are radioimmunotherapy and brachytherapy.
Treatment of cancer through chemotherapy involves the use of drugs to kill cancer cells. Unlike surgery and radiation therapy which kill cancer cells in a certain area, chemotherapy works throughout the entire body. This implies that it has the ability to kill cancer cells that have spread to other parts of the body away from a primary tumour. The objectives of chemotherapy in cancer treatment are to cure, control and palliate.
Chemotherapy can cure cancer by destroying the cancer cells. However, most doctors describe chemotherapy as a cure only when it has the ability to destroy cancer and prevent them from coming back. This is because it is not guaranteed that the patient will be completely destroyed. In case, chemotherapy fails to cure cancer, it may be used to control the disease. This is done by shrinking tumours and preventing cancer from growing and spreading. This enables the patient to live longer and healthier. In most cases, cancer patients don't get cured completely and therefore it is controlled and managed just like other chronic diseases such as diabetes and heart diseases.
Chemotherapy can also be used to ease cancer symptoms. This is called palliative chemotherapy. Palliation is done when the cancer has spread and is out of control. It basically improves the health of the patient in order to make them feel better.
Immunotherapy involves the treatment of cancer using certain parts of a patients immune system. This is involves the stimulation of the immune system of the patient to work harder by adding immune components into the body of the patient. An example of these components is the man-made system proteins. Immunotherapy may boost the immune system or train the immune system of the patient to fight cancer cells.
However, this type of cancer treatment is less effective since the immune system faces challenges targeting cancer cells. This is because cancer starts to spread once body cells have been altered and weakened. Body cells then fail to recognise cancer cells as foreign leading to its spread.
