Removing your fallopian tubes may decrease your risk for ovarian cancer

Research has shown that the majority of ovarian cancer arise from fallopian tubes, not ovary.  You may happen planning to have your uterus removed (hysterectomy) for non-cancerous reasons (fibroid, pain, excessive bleeding, etc).   And if you are a young woman, most of your surgeon would recommend preservation of your ovary/ovaries while removing your uterus.  A 2015 paper from Obstetrics and Gynecology journal showed that concurrent prophylactic removal of your fallopian tubes could reduce your ovarian cancer by 50%.

The removal of your fallopian tubes usually take only a few extra minutes.  Most surgeons do not even charge extra to do this.  There is a small risk of compromising blood perfusion to the ovary.   Please discuss with your surgeon if you plan to have hysterectomy for benign (non cancer) reasons.

New HPV vaccines to prevent genital dysplasia and cancer (available start Feb 2015)

Human papilloma viruses (HVP) are known to cause cancers.  In the genital areas, HPV cause the majority of cervical cancer (>90%) and some vulvar, vaginal, anal and penile cancers.   In 2015, there is a new HPV vaccine called 9valent HPV vaccine (from Merck).   In the past, there were 2 HPV vacciness covering HPV 16,18 and HPV 16,18,6,11.  This new vaccine covers 9 different HPV types thus further protect patients from potential genital cancers.

This new vaccine, similar to the previous HPV vaccines, are administered at 0, 1-2 months, and then 6th month (3 doses).  Vaccination can be started as early as 9 years old to age 26 (females) and 21 (males).  Men who have sex with men and immunocompromised men (HIV) can be vaccinated up to age 26.

You could find out more information from CDC.gov or your physicians and other health care providers.

Morcellator (tissue grinder) and uterine fibroid and risk of spreading cancer

With wide spread surgical practice using robot or laparascopy hysterectomy, many surgeons have to work with large uterine mass.  Most of these uterine mass are fibroid (benign smooth muscle tumor).   Thus, the surgeons would use a morcellator (like a grinder) to make the uterine mass smaller so they could be removed laparascopically (without making large surgical skin incision).

Unfortunately, not all uterine masses are fibroid and it is difficult to tell before surgery which one actually has uterine cancer.   If you use the morcellator on uterine cancer, then you may have the cancer spreads on your pelvis and abdomen.   Because of some rare cases that have occurred, many surgeons are becoming more cautious about using morcellators.   Please discuss with your surgeon if you have large uterine mass and you are about to undergo hysterectomy.  You may want to choose open abdominal approach than laparascopic or robotic hysterectomy.

Chemotherapy before surgery in patient with ovarian cancer

In some patients with ovarian cancer, unfortunately,  the cancer spreads widely that surgery cannot remove most of the tumor.   A randomized trial reported of using neoadjuvant chemo (chemo before surgery) first for 3 months to shrink tumor to smaller size, then surgery.   In my experience, this approach works especially well on patients with a lots of tumor and ascites (fluid in abdomen) which put patient at high risk for surgical complications.   Some patients, due to extensive tumor, may need longer than 3 months of neoadjuvant chemo.  Although chemotherapy itself has its own side effects, some patients seem to better tolerate surgery after, rather than before chemo.

If you have widespread ovarian cancer with ascites, you may want to discuss this neoadjuvant chemotherapy approach with your doctor.
