Cancer cells grow and divide faster than other normal cells. That's why destroying these cells is the most important thing for this treatment. This process works by making small cracks in the DNA inside the cells. This creaking keeps cancercells from growing and dividing and causes them to die faster. People don't need to worry about their normal cells' affection because radiation is very focused on the cancer affected area.

The External radiation treatment -

This therapy treatment is also known as External-beam radiation therapy, which mainly delivers radiation from a machine outside the body to treat cancer. It is the most common treatment. It just takes 15 mins. Patients need these treatment sessions five times per week. most of the times.
In some cases the radiation treatment is given on alternate day basis or once a week.

The Internal radiation treatment -

In this treatment process, the radioactive source is put inside the patient's body into or near the tumor. This therapy treatment is also well known by brachytherapy. This treatment needs to have repeated therapies across several days and weeks. But the good thing is people don't feel any discomfort during this treatment.
