(TEGNA) — Selma Blair is giving a health update to fans after being diagnosed with multiple sclerosis nearly a year ago.

During a Time 100 Health Summit, the 47-year-old actress discussed her latest treatments including chemotherapy and a stem cell transplant to help combat the disease.

"I was declining more rapidly than I found acceptable," Blair said.

Before her stem cell transplant, Blair said she was given a "microdose" of chemotherapy and instantly felt relief, convincing her to continue with the operation despite the major risk.

"Why would I put this horrible drug in [my body] — chemotherapy. I was out of options and was looking," Blair said.

Blair added that she made plans for her death, given the risk involved in the stem cell transplant.

According to the MD Anderson Cancer Center, a stem cell transplant is a procedure in which damaged cells are replaced with normal blood cells — an operation done to treat MS.

"Overall, it went pretty smoothly," Blair said after going through the treatment.

Knowing what she knows now, Blair wishes she took small signs during her 30s as a sign.

"Looking back I would have asked for an MRI, I just didn't ask for that simple tool and no one thought to give it to me," Blair said.

Blair was praised by panel moderator Dr. David Angus, for how open Blair has been during the process.

"Stepping out and saying I have a disease and not being embarrassed by it, but living with it and being a model for every other person who think they have symptoms or has the disease is so powerful and so needed in this world," Angus said.

Last October, Blair announced her diagnosis in an interview in an Instagram post. In an interview with ABC News last February, she said that she cried after finding out she had MS, because she finally knew what was wrong with her after years of declining health.

I was in this wardrobe fitting two days ago. And I am in the deepest gratitude. So profound, it is, I have decided to share. The brilliant costumer #Allisaswanson not only designs the pieces #harperglass will wear on this new #Netflix show , but she carefully gets my legs in my pants, pulls my tops over my head, buttons my coats and offers her shoulder to steady myself. I have #multiplesclerosis . I am in an exacerbation. By the grace of the lord, and will power and the understanding producers at Netflix , I have a job. A wonderful job. I am disabled. I fall sometimes. I drop things. My memory is foggy. And my left side is asking for directions from a broken gps. But we are doing it . And I laugh and I don’t know exactly what I will do precisely but I will do my best. Since my diagnosis at ten thirty pm on The night of August 16, I have had love and support from my friends , especially @jaime_king @sarahmgellar @realfreddieprinze @tarasubkoff . My producers #noreenhalpern who assured me that everyone has something. #chrisregina #aaronmartin and every crew member... thank you. I am in the thick of it but I hope to give some hope to others. And even to myself. You can’t get help unless you ask. It can be overwhelming in the beginning. You want to sleep. You always want to sleep. So I don’t have answers. You see, I want to sleep. But I am a forthcoming person and I want my life to be full somehow. I want to play with my son again. I want to walk down the street and ride my horse. I have MS and I am ok. But if you see me , dropping crap all over the street, feel free to help me pick it up. It takes a whole day for me alone. Thank you and may we all know good days amongst the challenges. And the biggest thanks to @elizberkley who forced me to see her brother #drjasonberkley who gave me this diagnosis after finding lesions on that mri. I have had symptoms for years but was never taken seriously until I fell down in front of him trying to sort out what I thought was a pinched nerve. I have probably had this incurable disease for 15 years at least. And I am relieved to at least know. And share. 🖤 my instagram family... you know who you are.
