Been there done that. I am very sure that excessive stress, working too much and not being self aware caused cancer. Including nutrition.

I am Indian and when my mom first learned I had breast cancer, she said 2 things. It was God’s fault and its because I was over weight. My response was, if the last part were true, many more men would have breast cancer.
The diagnosis and recovery has been a journey. Listening to feedback, educating others, sharing what I did, etc.

I was interviewed for a cancer podcast asking how did I process the diagnosis, manage my emotions and manage cultural bias. I definitely think emotion plays a big role making the best decision, and without listening to other emotional people.
