So glad we're continuing our series change in a flash. It takes a closer look at menopause here in the U.S. And women start ex-pierpsing it at the average age of 51. One in every hundred women will experience it prematurely and we know all too wells cancer treatment can also bring on early menopause. Exactly. For some young women that cancer diagnosis also means the shock of going through what's known as chemically induced menopause. Something I experienced, something robin experienced and the woman you're going to meet is struggling with the very same thing. Samantha Reese was only 32 years old when she was diagnosed with cancer. To be perfectly honest, I felt like I got kicked in the stomach because I wasn't even old enough to start getting yearly mammograms. Reporter: The los angeles-based makeup artist undergoing treatment and starting medications that shut down her ovarian function chemically inducing menopause. My very first feelings were like my dreams of having children were slipping away. Reporter: Reese quickly feeling one of the telltale symptom, hot flashes. It literally felt like the Gates of hell opened up and it was being blown directly into my face. Reporter: One in every 100 women experiences what is known as ovary insufficiency or premature menopause by the time she turns 40. Ovarian surgery, chemotherapy or radiation are some of the possible causes but can be caused by thyroid problem, autoimmune disease or family history. I didn't realize I was out of time.

And I'm like you're just scaring me and I went -- yeah, they're like, you have one egg. It was bleak. Reporter: As for Samantha she and her fiance plan to try in the next few years when doctors allow her to pause her medications. There are tons of women who have gone through what I'm currently going through and went on to have beautiful healthy babies and also not have a recurrence of their cancer so I have plenty of reason to be hopeful. You know, I haven't spoken much about this because when early menopause happens as a result of chemo all you're focused on are the cancer treatments and surviving. You're not even thinking about it but today four years later I am still struggling with the effects of menopause. I'm not surprised. No. So, you know, with early or chemical menopause -- This is Dr. Kristi funk, the -- I know. Talk about it.

It seems not to have affectedb you. The hot flashes are by the far the worst and severe and happened all the time. The night sweat, irritability. Trouble sleeping. And I've noticed a huge change in my skin. A huge change in my sn. Many women have experienced even before menopause that there's some Sims. Change before the change.
