Scaried about bottle reuse. Get cancer?

I had bought 2 mineral water bottle (bisleri)then i started reusing them i reused them for 20 days after that i removed their plastic label i found that one bottle had very very small jelly like sticky solid plastic(probably only on outside not on inner surface)but i still reused it for 25 days after that i felt its not right so i threw that bottle however in these 45 days i never put boiled water in these 2 bottle they were never exposed to sunlight and were stored at room temperature and maximum water would last in these bottle for 2or3 days not more than that.However i still was using 2nd bottle which was in right condition and i used it for 20 more days.Again in these 20 days bottle was stored in room temperature i never put boiled water in it and only 2to3 days the bottle was exposed to sunlight that too for 20to30 minutes and maximum water would last in it for 2 days.After that i came to that these bottle leach chemical so i threw the bottle.i am scaried will i get cancer??
