Cancer is really a terrible disease that makes life looks miserable, this disease when it attacks a person, it attacks with full hearted and doesn't want to give the patient a peace of mind. Cancer has taken the life of people from different categories without thinking twice. Cancer has different kind and it can attack from different places, I feel sorry for your close friends (the lady and the neighbor) who unfortunately die because of cancer.

I agree with you, the world will be much better if we have the chance to eradicate disease like cancer. Stay safe.
