The fortune teller said that we would grow old together, but he had cancer.

Mainly because the fortune teller guessed that I would answer this question.

Cancer in this world is not incurable, but first you have to understand one thing, and that is why you get cancer. All these things have a cause and effect. Now I'll tell you the cure for cancer, regardless of your cause and effect. The classics used to treat diseases in Buddhist scriptures include the Pharmacologist's Classic, the Tibetan Classic, and the Quan Jing of Guanyin. Reading these classic works is of great benefit. I pray to all sentient beings in ten directions, hoping to cure your husband's cancer, and then cure the disease with one heart and one mind. The power of immortals is great, provided that you know the truth of being a man, so I recommend you to read Disciples Rules and be kind. This is not a superstition, but a true fact, and it is also the most suitable way for you at present. If you devote yourself to Buddhism, you will be able to grow old together. Recite the above classics every day, repay all sentient beings in the dharma circle, and sincerely wish you good health and all the best.
