Recently diagnosed with grade 3A Serous Endometrial Carcinoma

I was diagnosed in August with invasive endometrial cancer here in Ontario, Canada.   I have not found a forum like this yet at home for womb cancer.   I had a hysterectomy with removal of ovaries, fallopian tubes, omentum and pelvic lymph nodes.  I had two rounds of paclitaxel and carboplatin so far of the 6 that were planned. I am 67.  All this has been quite a shock.  I am relieved to find support and information from people who have been through this or are going through this now.  I am considering not doing radiation therapy.
