Is someone who already had cancer more prone to get it again?
If somebody had cancer, but they've been in the clear for it reoccurring, are they still prone to other cancers? Is it easy to get that type of cancer again?
Also, when it comes to machines and shots and all that stuff that can cause cancer, will it be easier for a person who already had cancer to develop cancer again from these things than people who haven't? (Ex. Somebody who had cancer in the sun versus somebody who hasn't, would the person with cancer be more likely to develop cancer from the sun than the person who didn't have it?)
I’m not sure what you are referring to.
“Machines and shots and all that stuff that can cause cancer” – machines and shots do not cause cancer.
There are more than 200 diseases called cancer, some do make you more prone to a second primary and some do not. Sometimes treatment makes you more prone to a second primary and some treatment does not.
Of you are referring to a recurrence it is not a second cancer it is the same one and that depends on the type of cancer you had, the stage, the grade and the treatment received.
EDIT: Again machine and shot DO NOT cause cancer.
2: Sun exposure increases your chance of getting skin cancer. Even if one tumor is successfully treated, your skin is still damaged and your risk of skin cancer is higher.
3: Chances of getting recurrence of primary cancer are more.
Otherwise chances of getting ca. are same as to other person exposed to carcinogens.
*By machines and shots, I mean that certain things have been proven to have a high risk of cancer. It's rare in shots, but it can happen. For machines, some give off radiation, like those full body scanners in airports.
