need some help here for the following 2 questions.
1.
I'm kind of stuck on this below (in quotes) in terms of the percentage increase, what does it mean by baby powder (BP) increases 30% in ovarian, but the risk only increases from 1.6% to 1.8%, how can 30% turn out to be 1.8%? 1.8% sounds a lot more pleasant than a 30% increase. sorry that I might seem not to bright on this calculation. I don't know how that calculation was done.
2. they said those who had their ovarian removed and if their ovarian cancer was caused by BP, BP(talc) will be found in the ovary, but how do they prove that the BP (talc) was the particle source to form the tumors and not due to other reasons to cause the tumor to form, but just so happen the BP (talc) was just happened to be on the tumor? I know this might be too difficult to answer.
3. I will stop using BP, but after using it for 20+ years, I am very fearful now that it might be too late and I would have tons of talc stuck in my ovary.
quoted. "
16 studies published before 2003 found about a 30% increase in ovarian risk among talc users. The average woman's lifetime risk of ovarian cancer is about 1.4%, so even with a 30% increase, her lifetime risk would be about 1.8%. "
One of the difficult things for people without a statistics background to understand is the difference between relative risk and absolute risk.
Here, the relative risk is the 30% increase, which sounds like a lot. But what that means is that the actual number of women potentially affected by the talc is 0.3 times the average: 1.4% times 0.3 is 0.42%. We now have to add that increase to the baseline overall average: 1.4% + 0.42% = 1.82%.
So overall about 14 women in a thousand will get ovarian cancer, and about 18 in a thousand exposed to talc will get cancer. The absolute risk we can attribute to talc would be 18-14= 4 in a thousand. Very small.
That is if that 30% increased risk is even true, and there are researchers who doubt it.

It can do so without causing any symptoms at all. This is different from repeatedly inhaling baby powder or ingesting it.
There are also medical uses for talc inside the body. Those uses have not been associated with cancers.
I don't know the women who found talc in their ovary cancer tumor and file law suit, how exactly did they apply the baby powder? I've been putting the baby powder on my underwear, I never forced it inside of me, but by sitting down, is it possible that it still could travel all in way in to my ovaries? I don't think it's possible. is there a test to see if I do have talc in my ovaries?

Most women apply it directly to the skin, but contact between the skin and your underwear would enable it to migrate into the vagina.
There is no test short of surgically removing the ovaries to tell if talc is there.

Yeah, I don't know how successful those suits will be when there are experts who will testify that the correlation does not prove causation.
In this case, talc was found in the patient's tumor, which might be a more compelling argument for causation:
I used to use it all the time but then I became allergic to everything "Scented" so I needed to use unscented things..like cornstarch. Now I don't use anything at all, because I have open/draining wounds from a serious skin disease...but I did find vagisil powder to be very helpful with itching and burning. Even though it has a scent to it, it is hypoallergenic.

did you used to put BP in between your
inner side of your legs to keep dry and so like when I walk, it's more comfortable,
I also put some in my butt area. however, I put a lot and a lot goes to my underwear.
Was this how you applied it before too and do u worry about getting OC from doing so?
