High-grade cancers have cells that look very different from normal cells and are arranged differently. They tend to grow more quickly and are more likely to spread.

Is high grade cancer bad?

How fast does high grade serous carcinoma grow?

Recent research has found that high-grade serous cancers that begin in the fallopian tubes take on average 6.5 years to progress to the ovaries, and then spreads to other areas quickly. These advanced carcinomas typically spread to the peritoneum first (lining of the organs of the pelvis and abdomen).
