Me no understand. Why cancer exist?

If clever doctor people read books and do complicated experiments, cancer no exist. Me optimistic about future in spite of admittedly limited understanding of scientific concepts. Me express curiosity about diseases with FISTS. Me smash!

Me admit to ambivalent feelings when me think. If me smash planets, me bad too? What happen to people when planet booms? Ouch. Think hurts! When brain made of semi-soft non-aged cheese, think difficult. Think hurts! No think, me!

Mr. Mozzarella supports your donations to cancer research and one day apires to be capable of expressing his feelings verbally with a higher level of precision, although he admits that attacking things with his fists is a source of enduring gratification and is not currently planning on seeking alternative outlets for his not inconsiderable levels of pent-up rage.

Every book you buy contributes to cancer research

As of World Cancer Research Day - 24 September 2025 - and permanently, I will donate 10% of my royalties from each sale to cancer research.

• Sales in Spain → donations will go to the Spanish Association Against Cancer (AECC).

• International sales → donations will go to the International Agency for Research on Cancer (IARC), part of the World Health Organization.

I’ll update the running total here approximately every three months.

• Where your donation goes:
  AECC (Spain): The Spanish Association Against Cancer has spent over 70 years supporting patients, families, and funding cancer research projects in Spain.

• IARC (international): The International Agency for Research on Cancer is a leading global body that studies the causes of cancer, develops prevention strategies, and coordinates international research.

This way, your purchase supports both global research and local initiatives in Spain.

How much is donated?
Kindle eBook - approximate donation (10%) ~£0.35 / $0.40
Paperback - approximate donation (10%) ~£0.45 / $0.55

Donations are calculated from my royalties (what Amazon pays me), not the full retail price. This way, no matter where you buy in the world, 10% goes to cancer research.

International sales
Whether you’re buying in the UK, the US, Australia, or any Spanish-speaking country, your purchase counts. Prices may vary slightly by country, but the donation percentage is always the same.

FAQs

Do I need to do anything special to make a donation?
No. The donation is automatic. Every sale counts.

How often do you update the donation figures on this page?
I update the total approximately every three months. This way, you can see the cumulative impact of your support without me needing to update it daily. Each update will reflect the donations sent to IARC during that period.

Why AECC and IARC?
Because cancer is both a global and local issue: IARC coordinates research worldwide, while AECC funds projects and provides support in Spain.

Thank you!
