Skin Cancer Radiation –
Skin cancer is contracted by several people each year. The major cause for skin cancer is the
prolonged exposure to the harmful ultraviolet rays. Ultraviolet rays affect cell division process consequently
leading to rapid increase in the cells of the skin, causing malignant tumors to grow. There are mainly three types
of skin cancer:
The last two are commonly
known as non- melanoma.
If detected at the early
stages skin cancer is easily curable. The common ways to treat skin cancer are
Skin cancer is treated
using radiation and this therapy is normally known as the radiotherapy. During such skin cancer treatment the radiation is focused on a target area. This high
power beam destroys the cancer cells and reduces the size of tumor. The radioactive rays destroy the
ic codes which result in the death of the cancerous cells. After radiation the normal cells recover but malignant
cells do not.
The main type of skin cancer radiation used is X-rays. These X-rays are produced at different
levels of energy. There are high energy radiations that burn off the malignant cells and tissues. These
radiations are able to penetrate in to the body and are commonly used to cure internal cancers. X-rays with low
energy are used for skin cancer treatment. These X-rays, that are
low in energy, are commonly known as the ortho voltage or superficial x-ray.
Types of Radiation
The radiotherapy is
In the case of skin
cancer, external therapy works well.
Benefits of Radiation
purpose of radiotherapy is to destroy skin cancer cells without causing least possible damage to normal cells.
It is a curative treatment that, in most of the cases, imparts long term benefits. Depending over the enormity
of skin malignancy, radiotherapy is given as an independent treatment or in conjunction with one or more
treatments. Radiotherapy can be pre-operative as well as post-operative depending on the case. Its main aim is
to shrink the existing malignancy and also hinder further proliferation.
Factors to be looked into
before commencing Radiotherapy
All skin cancers cannot be
treated with radiation therapy. There are certain aspects that need to be looked into before commencing the
Type of cancer the person is
affected with – The type of the cancer is
the main factor that decides if radiotherapy would be pertinent or not. While
melanoma cancer is not very receptive to radiation therapy, the non melanoma cancer is sensitive to
The area affected by
The area affected with cancer is also an important factor that decides if radiation therapy would be successful or
not. The sensitive areas of the body which are prone side effects are not treated using radiotherapy. Eyelids
lower portion of legs are some areas where radiation therapy cannot be used.
The medical history of the
patient – If the patient has already
taken radiation treatment and cancer has resurfaced then it is not advisable to go for it
