My most dear, most kind, most precious, wish-fulfilling one,

There is a method, which is to have butter blessed with mantra by a good practitioner. This could be a layperson or a monk. Then put the butter inside [your body] where the cancer is, if this is possible. Do that a few times a day. Depending on where you are based, I can check if there are any lamas around who can do this.

Actually, you can do it yourself also. So you can recite some malas of OM MANI PADME HUM every day—you have ten spoons of butter and after each mala blow on the butter or even spit on it, but you have to visualize yourself as Chenrezig if you have received that initiation. If you haven’t received that initiation, then visualize Chenrezig at your heart.

If you have received teachings from His Holiness the Dalai Lama, then think Chenrezig is His Holiness the Dalai Lama, your guru, and think the butter is being blessed by His Holiness the Dalai Lama/Chenrezig, then apply the butter two or three times a day.

Begin by generating bodhicitta motivation. Visualize the butter as completely blessed energy purifying all the four things: negative karma, disease, spirit harm and obscurations. You should feel that your body is totally filled with blissful purifying energy. Concentrate on that and at the end make strong dedications

You need to read the Arya Sanghata Sutra five times and the Golden Light Sutra four times.

Also, recite the Most Secret Hayagriva mantra. If you have the short meditation, you can do that with the mantra. You cannot arise as the deity unless you have already received the initiation; instead you visualize the deity above your crown. First it is most important to have bodhicitta motivation.

To have surgery for the cancer came out best. In regards to what you can do, try some meditation on emptiness. This is the best thing you can do. You can find the four vital points of analysis in Liberation in the Palm of Your Hand.

Meditate on how you are empty and how the cancer is empty, so use different techniques.

Also do strong meditation on bodhicitta. Please try this. I am also making prayers for you.
