Two days to my birthday guys! Please donate generously, she posted on micro-blogging site Twitter. Sonam says shes proud to be a part of the foundation. "It is my privilege to be associated with Ogaan Cancer Foundation and play a part in spreading breast cancer awareness. Everyone seems to know someone with breast cancer - I lost an aunt to it. I'm very happy to support the OCF team, which has shown earnestness and a sense of dedicated purpose, she said. I hope I can make a difference in my own way. Therefore this year on my birthday I urge friends, family and fans who wish to gift me to do so by donating to this cause, she further posted, she added.
