Nope. It's because pink is identified with the feminine. That's why the blue ribbon, and the blue/pink ribbon exist.
https://en.wikipedia.org/wiki/Pink_ribbon :
"The color
pink is considered feminine in modern Western countries. It evokes traditional feminine
gender roles, caring for other people, being beautiful, being good, and being cooperative.
The pink ribbon represents
fear of breast cancer,
hope for the future, and the charitable goodness of people and businesses who publicly support the breast cancer movement.
[7] It is intended to evoke solidarity with women who currently have breast cancer.
Breast cancer organizations use the pink ribbon to associate themselves with breast cancer, to promote breast cancer awareness, and to support fundraising.
[8]Some breast cancer-related organizations, such as Pink Ribbon International,
[9] use the pink ribbon as their primary symbol.
Susan G. Komen for the Cure uses a stylized "running ribbon" as their logo.
[10]
While specifically representing
breast cancer awareness, the pink ribbon is also a
symbol and a
proxy of goodwill towards women in general.
[11] Buying, wearing, displaying, or sponsoring pink ribbons signals that the person or business cares about women. The pink ribbon is a marketing
brand for businesses that allows them to promote themselves with women and identify themselves as being socially aware.
[12] Compared to other women's issues, promoting
breast cancer awareness is politically safe"
