Suzanne Somers was often criticized for spreading misinformation about various health and wellness claims, including her approach to chemical-free treatment for breast cancer.

Healthline wrote a detailed article about her approach to treatment and provides more background to some of the treatment option pros and cons:

It's always sad to lose someone to breast cancer, especially a bubbly personality who came into our living rooms via the television. I do worry however about the influence stars can have on spreading non-evidence based treatment approaches. It's scary when people listen to TV or movie fame for guidance in health.

As always, I feel obliged to remind everyone to discuss any alternative or completmentary therapy options with your cancer care team. Inquire about Integrative Cancer Care at your cancer center

@kseanob, thanks for allowing me to vent a little. I realize that you are asking about Suzanne Somers for a different reason. Hearing about the passing of a celebrity brings the reality of cancer back home and I can understand your concern that this could trigger worry in your daughter. For Somers, she lived with cancer for over 20 years, moving from remission to recurrence several times from what I could find. I did not see any information (yet) about type of breast cancer or stage.

I think it is important to let your daughter know that there are many different types of breast cancer and that everyone's experience is different. How do you help reduce your daughter's worry? That must be hard.
