electrons
protons
neutrons

protons

Explanation:

Protons are positively charged elementary particles of hydrogen atom nuclei, and have a much greater weight than that of electrons.

In this sense, proton therapy consists in pointing to a tumor with an invisible and highly controlled beam that works with precision as if it were drawn with the tip of a pencil.

It should be noted that, firstly protons are accelerated inside a cyclotron at a speed that is equal to approximately half the speed of light (allowing them to have high energy) allowing the damage to tumors up to a depth of approximately 30 cm.

After the protons are accelerated in the cyclotron, they are directed with a strong magnetic field to a very narrow beam and transferred with a high degree of precision through the malignant tumor. This high amount of energy released in a controlled manner in the tumor tissue, results in ionization and damage to the DNA of the malignant cells that are attacked, causing them to stop dividing rapidly (the cause of cancer) or even causing the cells to die, immediately

This is a highly effective treatment that has no side effects in damage to healthy tissue surrounding the tumor, unlike X-ray therapies.

as technology advances, new experiments often expose problems in accepted theories. c
