mass number (A) the number of nucleons (protons plus neutrons) in the atom of a nuclide; generally indicated by a superscript preceding the symbol of a chemical element (e.g., 131I), denoting a specific isotope.
oxidation number a number assigned to each atom in a molecule or ion that represents the number of electrons theoretically gained (positive oxidation numbers) or lost (negative numbers) in converting the atom to the elemental form.

Avogadro's number  (N ) (N A) the number of molecules in one mole of a substance: 6.023 × 1023.
mass number  (A ) the number expressive of the mass of a nucleus, being the total number of protons and neutrons in the nucleus of an atom or nuclide.
oxidation number  a number assigned to each atom in a molecule or ion that represents the number of electrons theoretically lost (negative numbers) or gained (positive numbers) in converting the atom to the elemental form (which has an oxidation number of zero). The sum of the oxidation numbers for all atoms in a neutral compound is zero; for polyatomic ions, it is equal to the ionic charge.

Q. what is a safe tumor marker number range?

A. depends on the marker...most of the markers are materials that found normally in our body. and there are a number of markers and their levels differentiate. what marker do you mean?

Q. What are the percentage of people dealing with breast cancer out of the number of people that are illness with cancer ? and what is the percentage of death cases out of sum of all cases of breast cases ? is there any difference between the amount of death cases from breast cancer and than the other kinds of cancer ?

A. here's a quote from the CDC site:
"Aside from non-melanoma skin cancer, breast cancer is the most common form of cancer in women. Breast cancer is the number one cause of cancer death in Hispanic women. It is the second most common cause of cancer death in white, black, Asian/Pacific Islander, and American Indian/Alaska Native women."

Q. i have heard that number of scientists found out in one of there researches that breasts Cancer is capable to just disappear with out a treatment , have any one read this article/research ? or maybe just heard about it ? because it is interesting why and how this result happens ...

A. hi pinkofdestiny - try also these links, i know and read a lot about the books of Phillip Day and recommend them to everybody. cancer can be healed and there are also ways to make with success prevention:

http://www.credencegroup.co.uk/Eclub/ses/sessearch.php?q=breast+cancer&pvdc=0

before a woman should loose her breast, she should make a therapy with vitamine B17 - the vitamin which can eliminate cancer in any form, but you should not know about it! it is terrible, but it is the way how politicians and industry-trust treat us.
