To kill cancer cells, if aimed properly.

The radiation kills malignant cells thus destroying cancer. A newer technology called Photodynamic Therpay (PDT) has been more specific in the sense that the exposed radiation selectively attacks only cancerous cells that have absorbed a photo-active compound a day earlier. This selective photo-oxidation is localized to cancerous areas only and does not indiscriminately affect other parts of the body.

Short story: The goal is to damage cells to trigger apoptosis (cell death). Cells are more sensitive to damage while dividing and because cancer cells are typically dividing rapidly, they are more sensitve to radiation.

Application of radiation in medicine (radiation therapy) such as in cancer treatment helps to kill cancer cells and shrink tumors.

Radiation therapy slows the progression of cancer by killing cancer cells. Please take a look at the following RG links and a PDF attachment for more details.

Radiotheraphy has an important purpose in cancer treatment - to kill cancer cells or to slow their growth by damaging their DNA.

Radiation therapy is an important tool for treating cancer patients. The main purpose of radiation therapy are to shrink tumors and kill cancer cells by using chemotherapy.

Thanks a lot for your elegant answers.

Ideally, the target of irradiation is the death of cancer cells. But it is important to know what type of exposure is being used.

Thank you Dr Oleksii Lonin

Radiation therapy used to reduce tumors and kill cancer cells.

Radiation Therapy to Treat Cancer. Radiation therapy (also called radiotherapy) is a cancer treatment that uses high doses of radiation to kill cancer cells and shrink tumors.

Radiation therapy is a treatment used for cancer and, less commonly, thyroid disease, blood disorders, and noncancerous growths. It can have a targeted, powerful effect on tumors that are confined to a specific area.

The form of radiation used in cancer therapy is a high-energy type known as ionizing radiation. Radiation works by making small breaks in the DNA inside cells. These breaks keep cancer cells from growing and dividing and cause them to die.

The purpose of radiation is to kill cancer cells . However radiation may give relief but to keep the patient under calm & control manner . I have expressed my views sometimes back which I submit herewith for your kind perusal

I have already expressed my views in this respect which I represent for your information .

The word '' CANCER'' speak for the cancellation however with all the timely care under the treatment may certainly prevent the disease . For this the sufferer must control his mind & he/she should remain without frustration keep their mind calm & quiet for the healthy environment .

If the patient mind remains calm & quite he /she can certainly take recourse to spiritual faith healing & with the firm faith they may get necessary energy & vibration to keep the disease under the control .

This is my personal opinion

Radiation kills or slows the growth of cancer cells

External beam radiation therapy  is a local treatment, aims radiation at specific part of your body where there is cancer .

Brachytherapy is a type of internal radiation therapy in which seeds, ribbons, or capsules that contain a radiation source are placed in your body, in or near the tumor.

It all depends on the dose of radiation and time of exposure. Important is the accessibility of the organ to be irradiated and the frequency of exposures.

The reason radiation is good at treating cancer is that cancer cells do not have the ability to repair DNA damage as well as healthy cells do. This is why fractionation is commonly used, where the total dose is delivered in many smaller fractions. This allows healthy tissues to recover between exposures, whereas the cancerous tissue does not recover and the damage is cumulative. Note that some cancers are fairly resistant to radiation though and in many cases radiotherapy is not a cure.

Good responses so far.

In BNCT, radiation kill cancer cell but not the healthy cell

Hi

Its nessesery for eleminate the tomoric cells.

клітини пухлин надзвичайно чутливі до впливу іонізуючої радіації. Чим більш молода клітина (малодиференційована), ти більш вона чуьлива до іонізуючого опромінення. Підбирабючи види та дози опромінення для кожного виду пухлини в різних тканинах можно ефективно боротись з раковими клітинами

It's so clrearance thing. Thats eleminate the tumoric cells with radiation energy

Radiation Therapy to Treat Cancer

The purpose has been well known for decades.

Over the years, non-radiotherapy treatments have been identified for the treatment of cancerous diseases.

Unfortunately, most of these studies are being blocked by commercial interests in the field of radiotherapy.
