What is latency period in cancer?
The latency period for cancer is defined as the amount of time that elapses between the initial exposure to a carcinogen (cancer-causing substance) and the diagnosis of cancer.
How long after radiation exposure does cancer develop?
If cancer does develop after radiation therapy, it does not happen right away. For leukemias, most cases develop within 5 to 9 years after exposure. In contrast, other cancers often take much longer to develop.
What tissue is most susceptible to radiation induced cancer?
The breast seems to be one of the most susceptible organs for radiation induced cancer, but the A-bomb cohorts indicate a risk only in the younger age group (< 40 y at exposure). Except for the breast, the thyroid is the most susceptible organ in humans for radiation induced solid tumors.
What is the latency period for lung cancer?
Latency of lung cancer is 54.48 years for indoor air pollution, and 56.17 years for total smoking. From estimating latency period of lung cancer from multivariate analysis, it was found that the latency of lung cancer could be affected by the effects of other factors.
What cancer has the shortest latency period?
A latent period of decades may elapse between radiation exposure and the detection of cancer. The latent period for most cancers, including glioblastoma, is much longer than five years. The shortest latent periods, about five years, are for leukemia and thyroid cancer.
What is the latent period for thyroid cancer?
The mean and median latency period of papillary thyroid cancer was 30.1, 31.5 years, respectively. Thirty-three percent (19/58) of patients had a latency period of between 30 and 40 years.
What are the chances of getting cancer from radiation?
The risk of developing cancer from a lifetime exposure of background radiation is about 1 in 100, or 1% of the population.10It is impossible to avoid all background radiation, but the best ways to limit unnecessary exposure to radiation from the environment is to prevent your exposure to radon and repeated unprotected …
Which cancer has highest recurrence rate?
Some cancers are difficult to treat and have high rates of recurrence. Glioblastoma, for example, recurs in nearly all patients, despite treatment. The rate of recurrence among patients with ovarian cancer is also high at 85%.

Can you get cancer from radiation treatments?
Doctors have known for a long time that radiation can cause cancer. And research has shown that radiation treatment for one cancer can raise the risk for developing a different cancer later. Factors that can affect that risk include the amount of radiation used and the area that was treated.
Can radiation cause cancer later in life?
There is also a risk for other cancers, which are mostly solid tumors, after having radiation therapy. Most of these cancers develop 10 years or more after radiation therapy.
Which cancers are caused by radiation?
Cancers associated with high dose exposure include leukemia, breast, bladder, colon, liver, lung, esophagus, ovarian, multiple myeloma, and stomach cancers.
Can radiation from phones cause cancer?
Cell phones emit low levels of non-ionizing radiation when in use. The type of radiation emitted by cell phones is also referred to as radio frequency (RF) energy. As stated by the National Cancer Institute, “there is currently no consistent evidence that non-ionizing radiation increases cancer risk in humans.
What are the four types of therapies used to treat cancer?
The most common treatments are surgery, chemotherapy, and radiation. Other options include targeted therapy, immunotherapy, laser, hormonal therapy, and others. Here is an overview of the different treatments for cancer and how they work. Surgery is a common treatment for many types of cancer.

What does latency mean?
Latency is a measure of delay. In a network, latency measures the time it takes for some data to get to its destination across the network. It is usually measured as a round trip delay – the time taken for information to get to its destination and back again. … Latency is usually measured in milliseconds (ms).
