Can I claim a tax deduction for medical expenses for my father in Mumbai?

Hi, I need help. My father had a major surgery last month in Mumbai, and the bill was around ₹1,20,000. I heard I might be able to claim a tax deduction on medical expenses, but I’m not sure how it works. I’ve tried looking online, but the information is confusing. I feel frustrated because that amount would really help reduce my tax burden. What’s the process like?
