Ive only seen the previews, but the new movie 50/50 has already won me overfor at least two reasons. The first needs no explanation: Joseph Gordon-Levitts dimples. The second has less to do with my heart, and more to do with my head: the movie is evidence that the cancer conversation is not only getting louderits getting younger too.But if Im allowed one critique of this movie, its that Gordon-Levitts character isnt a woman. A woman with breast cancer.Despite popular perception, breast cancer doesnt just strike once youre over the hill. For about every 18 newly diagnosed cases, one is a woman under the age of 40. Its a group that often has more aggressive types of breast cancer and suffers higher mortality rates. Plus, young women are readily misdiagnosed or diagnosed at a later stage because doctorsand womenoften believe that your 20s and 30s are too young for breast cancer. While age increases your likelihood of acquiring the disease, by no means does youth grant you immunity from it.So whats a young,seemingly healthy girl to do?1.

For the better end! owed, so me areas can feel similar to a sandy beach and others similar to a lumpy bowl of oatmeal. Depending on the time of the month, you probably have changing levels of tenderness too.So be on the demeanour (er, feel) out for anything thats out of the ordinary foryou, and keep in mind that the dreaded lump isnt the only warning sign of breast cancer.
