Cancer refers to any one of a large number of diseases characterized by the development of abnormal cells that divide uncontrollably and have the ability to infiltrate and destroy normal body tissue. Cancer often has the ability to spread throughout your body. Cancer is the second-leading cause of death in the world.

Cancer occurs when changes called mutations take place in genes that regulate cell growth. The mutations let the cells divide and multiply in an uncontrolled way. Breast cancer is cancer that develops in breast cells. Typically, the cancer forms in either the lobules or the ducts of the breast. Lobules are the glands that produce milk, and ducts are the pathways that bring the milk from the glands to the nipple.

Cancer develops when there are changes to the DNA mutations within a cell that allow it to grow out of control. The cancerous cells can then crowd out normal cells or invade body tissues. Radiation, cancer-causing substances, infections, and your genetic makeup can raise your risk of mutations that result in cancer. Most people don't realize that cancer is preventable in many cases.

У всех такие… - На ней майка с британским флагом и серьга в форме черепа в одном ухе. По выражению лица панка Беккер понял, что тот знает, о ком идет речь. Мелькнул лучик надежды. Но уже через минуту парень скривился в гримасе. Он с силой стукнул бутылкой по столу и вцепился в рубашку Беккера. - Она девушка Эдуардо, болван.

Теперь только один человек в АНБ был по должности выше коммандера Стратмора - директор Лиланд Фонтейн, мифический правитель Дворца головоломок, которого никто никогда не видел, лишь изредка слышал, но перед которым все дрожали от страха. Он редко встречался со Стратмором с глазу на глаз, но когда такое случалось, это можно было сравнить с битвой титанов. Фонтейн был гигантом из гигантов, но Стратмора это как будто не касалось. Он отстаивал перед директором свои идеи со спокойствием невозмутимого боксера-профессионала. Даже президент Соединенных Штатов не решался бросать вызов Фонтейну, что не раз позволял себе Стратмор. Для этого нужен был политический иммунитет - или, как в случае Стратмора, политическая индифферентность.

Внезапно в гимнастическом зале, превращенном в больничную палату, повисла тишина. Старик внимательно разглядывал подозрительного посетителя. Беккер перешел чуть ли не на шепот: - Я здесь, чтобы узнать, не нужно ли вам чего-нибудь.  - Скажем, принести пару таблеток валиума. Наконец канадец опомнился.

 Проклятие! - выругался он, потянувшись к телефону сквозь сплетение проводов.  - Джабба слушает.
