Hello sir, my wife told me yesterday that there is a lump around her breast. What further steps should I take to determine if it is cancerous or not? As of now, the lump around her breast is painless. Do I need to visit an oncologist?

As per my understanding your wife is having a painless lump in her breast which is the cause of concern. You consult a surgeon first and get your wife thoroughly examined and evaluated .Only after that will it be clear what her diagnosis is and the required treatment will be advised. Consult Breast Surgery doctors in Mumbai, or in any other city.
