How Long Can You Live After Radiation Therapy?

Following treatment with stereotactic radiation, more than eight in ten patients (84%) survived at least 1 year, and four in ten (43%) survived 5 years or longer. The

median overall survival (OS) time was 42.3 months

.

Does radiation shorten your life?

“Rapidly dividing cells, such as cancer cells, are

more affected

by radiation therapy than normal cells. The body may respond to this damage with fibrosis or scarring, though this is generally a mild process and typically does not cause any long-term problems that substantially affect quality of life.”

What is the survival rate of radiation therapy?

The overall

5-year survival rate was 27%

. For 105 patients treated definitively with radiation therapy, the median and 5-year survival rate figures were 26.0 months and 40%. For 149 patients treated with adjuvant radiation therapy, the 5-year survival rate was 62% (median survival rate not reached).

How long does it take for cancer to die after radiation?

Radiation therapy does not kill cancer cells right away. It takes days or weeks of treatment before DNA is damaged enough for cancer cells to die. Then, cancer cells keep dying

for weeks or months after radiation

therapy ends.

Can you fully recover from radiation?

End-of-life care. A person who has absorbed very large doses of radiation has little chance of recovery. Depending on the severity of illness,

death can occur within two days or two weeks

. People with a lethal radiation dose will receive medications to control pain, nausea, vomiting and diarrhea.

Is radiation treatment worse than chemo?

Radiation therapy involves giving high doses of radiation beams directly into a tumor. The radiation beams change the DNA makeup of the tumor, causing it to shrink or die. This type of cancer

treatment has fewer side effects than chemotherapy

since it only targets one area of the body.

Does radiation harm your body?


Radiation can damage the DNA in our cells

. High doses of radiation can cause Acute Radiation Syndrome

Do tumors grow back after radiation?

Normal cells close to the cancer can also become damaged by radiation, but

most recover and go back to working normally

. If radiotherapy doesn’t kill all of the cancer cells, they will regrow at some point in the future.

At what stage of cancer is radiotherapy used?

Radiotherapy may be used in

the early stages of cancer or after it has started to spread

. It can be used to: try to cure the cancer completely (curative radiotherapy) make other treatments more effective – for example, it can be combined with chemotherapy or used before surgery (neo-adjuvant radiotherapy)

What is the next step after radiation therapy?

When your radiation therapy is complete, you will meet with your radiation oncologist for follow-up. Your next steps after that may include:

Meeting with other care teams for additional treatment

, if needed. Meeting with the cancer survivorship team for supportive care.

What happens if I refuse radiation treatment?

Patients who refuse recommended adjuvant radiation therapy have

unacceptably high rates of local recurrence

. Omission of radiation for advanced age alone is associated with local recurrence rates comparable to those for younger patients.

Does chemo and radiation treatments shorten your lifespan?

A large study has found that people who have survived cancer and its

treatment are more likely to die sooner

and have a shorter lifespan compared to those who have never had cancer.

How long after radiation do you start to feel better?

For most people, the cancer experience doesn’t end on the last day of radiation therapy. Radiation therapy usually does not have an immediate effect, and it could take

days, weeks or months

to see any change in the cancer. The cancer cells may then keep dying for weeks or months after the end of treatment.

How do you know if radiation therapy is working?

There are a number of ways your care team can determine if radiation is working for you. These can include:

Imaging Tests

: Many patients will have radiology studies (CT scans, MRI scans, PET scans) during or after treatment to see if/how the tumor has responded (gotten smaller, stayed the same, or grown).

What comes first chemo or radiation?

In the standard treatment sequence,

radiation therapy

doesn’t start until the chemotherapy regimen is done. The traditional external beam radiation therapy treatment schedule usually requires daily trips to the hospital or cancer center — usually 5 days a week for 4 to 6 weeks.
