What are the most common types of cancer caused by exposure to excessive amounts of radiation?
What about Leukemia and Thyroid cancer?Just go through the list of common types of cancer and identify ones caused at least in part by radiation. The top one is skin cancer by a factor of 10 over lung cancer. Skin cancer is exclusively caused by radiation. Lung cancer partly by radiation.
Maybe you should re-specify the initial question. As it was hinted before, 'radiation exposure' includes all kinds of radiation: UV from sunlight definitely included. And, indeed, within this context (radiation in general) the most frequent danger coming from sunbathing.What about Leukemia and Thyroid cancer?
Of course often that "skin" is in the interior of your lungAlpha and Beta as external radiation has limited penetration, usually only the skin is affected.
Statistical methods applied to populations allow firm conclusions to be drawn about populations however. This makes it difficult to successfully sue Kerr-McGee or the builders of Windscale for damages but Uncle Fred will still be dead.Because firstly we don't normally know the exact cause of an incidence of cancer.

Yep, and as a further addendum to this (this is a bit of a hijack, but I think it will be of interest):The effects of exposure on DNA were well known, the body's ability to recover from these effects were and are poorly understood.
In recent years however, there has been a shift, as now flash therapy is now being incorporated into many treatments -- this is where a large dose is delivered very quickly; in a fraction of a second. For reasons that are still unclear this leads to even better results in terms of the treatment effectiveness and minimizing damage to the healthy tissue. Research is ongoing, but in the meantime of course it makes sense to use this therapy even if we don't fully understand why it works.
Furthermore, before FLASH-RT is used clinically, two problems need to be solved. First, because of the differences between animal models and humans, the FLASH effect should be confirmed in cancer patients. Acute and late toxicity in different organs should be monitored. Second, because FLASH-RT can be completed in a single sitting, the definitive irradiation dose for different cancers needs to be redefined. Radiation oncologists should rebalance the effect of irradiation and healthy tissue toxicity and then define the radical irradiation dose. This may require the treatment of many cancer patients and a long time before this is satisfactorily defined. It may take many years before FLASH-RT becomes a mainstay radiotherapy technology in clinical applications.
