About 10% of cases are related to inherited genetic risk; women with mutations in the genes BRCA1 or BRCA2 have about a 50% chance of developing the disease. The most common type of ovarian cancer, comprising more than 95% of cases, is ovarian carcinoma.
A 512KB SDcard or flash memory stick can hold a bit less than three TV episodes (or one hour-long episode and some funny adverts, I suppose), or about 350 photos or 102 songs, which means about 10 CDs. A 1GB SDcard or flash memory device can hold twice that, and, of course, a 2GB device can hold twice that again. In other words, if you were to pony up for the 2GB device, you could store eleven 30 minute TV shows (or a couple of feature length movies), over 1300 photos, or 400 songs (aka 35-40 CDs).
Assuming that an average song takes up five megabytes, one terabyte could fit approximately 200,000 songs or 17,000 hours of music. How many songs do you have on your iTunes right now? Movies. You could fit approximately 500 hours worth of movies on one terabyte. Assuming each movie is roughly 120 minutes long, that would be about 250 movies. I do know people who have that many movies in their library, so it is possible that they could build a database of movies to fill that space. Pictures. You could fit approximately 310,000 photos in one terabyte. You could fit even more if you used a compression algorithm. How would you even catalog that many photos? By time, by subject, by category?
