Doctors of Kolkata invented that cigarette smoking is a cause of cancer and that means, the person who smokes cigarette will invariably be attacked by cancer but I do not know whether Sadhana used to smoke.
I saw all most all pictures of Sadhana. She acted with all top heroes at that time. Sadhana' s hair cut was most popular. Post death ceremony of Sadhana while compared with other names was found poor. Media has totally neglected her in communicating mass.
