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).
CDs can help transfer files between computers. A blank CD can typically hold about 74 to 80 minutes of music, which is generally not enough to hold 100 songs. But, a blank CD can also hold as much as 700 megabytes of data, which is usually more than enough for 100 songs. So the way to burn 100 songs on one CD is to do it as a data CD and not as an audio CD. A data CD won't play on most music players, but can be used to transfer music from one computer to another. A data CD can hold 100 songs.
