A Comprehensive Guide to Breast Cancer

Colon cancer develops when tumorous growths develop in the large intestine. It is now the third most common type of cancer in the United States. The colon, or large intestine, is where the body draws out water and salt from solid wastes.

The waste then moves through the rectum and exits the body through the anus. Colon cancer is also the third most common cause of cancer-related death in the U.

Healthcare professionals recommend attending regular screenings for colon cancer from the age of 50 years. Colorectal cancer , which describes co-occurring colon cancer and rectal cancer, is also common. Rectal cancer originates in the rectum, which is the final several inches of the large intestine, closest to the anus.

In this article, we look at how to recognize and treat colon cancer, why it develops, and how to prevent it. Colon cancer often causes no symptoms in the earliest stages. However, symptoms may become more noticeable as it progresses. These signs and symptoms may include :. If the cancer spreads to a new location in the body, such as the liver, it can cause additional symptoms in the new area. There are different ways of assigning a stage to cancer. The stages indicate how far a cancer has spread and the size of any tumors.

Treatment will depend on the type and stage of the colon cancer. A doctor will also take the age, overall health status, and other characteristics of the individual into consideration when deciding on the best treatment option.

There is no single treatment for any cancer. The most common options for colon cancer are surgery, chemotherapy , and radiation therapy. The aim of treatment will be to remove the cancer, prevent its spread, and reduce any uncomfortable symptoms.

Surgery to remove part or all of the colon is called a colectomy. During this procedure, a surgeon will remove the part of the colon that contains the cancer, as well as some of the surrounding area. For example, they will usually remove nearby lymph nodes to reduce the risk of spreading. The surgeon will then either reattach the healthy portion of the colon or create a stoma, depending on the extent of the colectomy. A stoma is a surgical opening in the wall of the abdomen.

Through this opening, waste passes into a bag, which removes the need for the lower part of the colon. This is called a colostomy. Here, learn more about endoscopy. During chemotherapy, a cancer care team will administer medications that interfere with the cell division process. They achieve this by disrupting proteins or DNA to damage and kill cancer cells. These treatments target any rapidly dividing cells, including healthy ones.

These can usually recover from any chemotherapy induced damage, but cancer cells cannot. A cancer specialist, or oncologist, will usually recommend chemotherapy to treat colon cancer if it spreads. The medicines travel through the whole body, and the treatment will take place in cycles, so the body has time to heal between doses. Combination therapies often use multiple types of chemotherapy or combine chemotherapy with other treatments.

Radiation therapy kills cancer cells by focusing high energy gamma rays on them. A cancer care team may use external radiation therapy, which expels these rays from a machine outside of the body. With internal radiation, a doctor will implant radioactive materials near the site of the cancer in the form of a seed. Some metals, such as radium, emit gamma rays. The radiation may also come from high energy X-rays. A doctor may request radiation therapy as a standalone treatment to shrink a tumor or to destroy cancer cells.

It can also be effective alongside other cancer treatments. For colon cancer, cancer care teams tend not to administer radiation treatments until the later stages. They may use them if early stage rectal cancer has penetrated the wall of the rectum or traveled to nearby lymph nodes. A physician will carry out a complete physical examination and ask about personal and family medical histories. They may also use the following diagnostic techniques to identify and stage cancer:.

A doctor will insert a long, flexible tube with a camera on one end into the rectum to inspect the inside of the colon. The colon will also require cleansing with strong laxatives in a process known as bowel prep.

If the doctor finds polyps in the colon, a surgeon will remove the polyps and refer them for biopsy. In a biopsy, a pathologist examines the polyps under a microscope to look for cancerous or precancerous cells. A similar procedure, called a flexible sigmoidoscopy, allows a doctor to examine a smaller portion of the colorectal area.

This method involves less preparation. Also, a full colonoscopy may not be necessary if a sigmoidoscopy does not reveal polyps, or if they are located within a small area. This X-ray procedure uses a liquid called barium to provide clearer images of the colon than a standard X-ray.

A person must fast for several hours before undergoing a barium X-ray. A doctor will inject a liquid solution containing the element barium into the colon through the rectum.

They follow this with a brief pumping of air to smooth over the barium layer to provide the most accurate results. A radiologist will then conduct the X-ray of the colon and rectum. The barium appears white on the X-ray, and any tumors and polyps will appear as dark outlines. If a biopsy suggests the presence of colon cancer, the doctor may order a chest X-ray, an ultrasound , or a CT scan of the lungs, liver, and abdomen to assess the spread of the cancer.

Following diagnosis, a doctor will determine the stage of the cancer based on the size and extent of the tumor, as well as the spread to nearby lymph nodes and distant organs.

People should also consider limiting their alcohol consumption and quitting smoking. Symptoms may not appear until the cancer has progressed. For this reason, the American College of Physicians recommend screening for people aged 50—75 years, including:.

Consult a doctor for recommendations. Usually, cells follow an orderly process of growth, division, and death. However, cancer develops when cells grow and divide uncontrollably, and when they do not die at the normal point in their life cycle. Most cases of colon cancer originate from noncancerous tumors called adenomatous polyps. These form on the inner walls of the large intestine. Cancerous cells may spread from malignant tumors to other parts of the body through the blood and lymph systems.

These cancer cells can grow and invade healthy tissue nearby and throughout the body in a process called metastasis. The result is a more serious, less treatable condition. The most common types of polyps are:.

Some of these polyps may grow into malignant colon cancer if a surgeon does not remove them during the early stages of treatment. A person might inherit a genetic predisposition toward colon cancer from close relatives, especially if a family member received a diagnosis before the age of 60 years old.

It is possible to have these genetic feature without developing cancer. This is because the cancer will not develop unless an environmental factor triggers it. Age is a significant risk factor for colon cancer. However, it is becoming more common in people under Colon cancer is more likely to affect people with inactive lifestyles, those with obesity , and individuals who use tobacco. As the colon is part of the digestive system, diet and nutrition play central roles in its development.

Low fiber diets can contribute. Also, according to one review , people who consume excessive amounts of the following have an increased risk:. Early detection and treatment are the most effective ways to improve the outlook for a person with colon cancer. In stage 4 colon cancer and rectal cancer , the liver is the most common site of metastasis. Colorectal cancer cells may also spread to the lungs, bones, brain, or spinal cord. Metastatic, or stage 4, breast cancer in the lungs is when breast cancer cells are growing in the lungs.

The symptoms of prostate cancer may be different for each man, and any one of these symptoms may be caused by other conditions. Because of the proximity of the prostate gland to the bladder and urethra, prostate cancer may be accompanied by a variety of urinary symptoms, especially in the early stages. Depending on its size and location, a tumor may press on and constrict the urethra, inhibiting the flow of urine. Some early prostate cancer signs include:. The prostate gland produces PSA, a protein that at an elevated level may be a sign of prostate cancer. A high PSA reading also may indicate noncancerous conditions such as inflammation of the prostate prostatitis and enlargement of the prostate benign prostatic hyperplasia.

Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. The risk of developing certain cancers can be reduced by not smoking, maintaining a healthy weight, limiting alcohol intake, eating plenty of vegetables , fruits , and whole grains , vaccination against certain infectious diseases, limiting consumption of processed meat and red meat , and limiting exposure to direct sunlight.

This video discusses the importance of knowing the signs and symptoms of gynecologic cancer. There is no way to know for sure if you will get a gynecologic cancer. If you have vaginal bleeding that is unusual for you, talk to a doctor right away. Any vaginal bleeding after menopause needs to be reported to your doctor. You should also see a doctor if you have any other warning signs that last for two weeks or longer and are not normal for you.

Hepatocellular Carcinoma - Future Outlook. Hepatocellular carcinoma HCC is often diagnosed after the tumor manifests clinical signs and symptoms. Early diagnosis is usually performed thanks to HCC screening programs for patients affected by liver cirrhosis or chronic viral hepatopathies using ultrasound and serum alfa-fetoprotien. In most HCC cases, clinical signs and symptoms of this tumor may occur several months after development, when therapy can not be curative, given the advanced tumor stage and underlying liver disease, which preclude curative options, such as ablation, resection, or liver transplantation. Clinical features of HCC are often similar to those caused by the underlying hepatic disease.

Когда она вошла, глаза немца чуть не вывалились из орбит. На ней была черная ночная рубашка; загорелая, орехового оттенка кожа светилась в мягком свете ночника, соски призывно выделялись под тонкой прозрачной тканью. - Komm doch hierher, - сказал немец сдавленным голосом, сбрасывая с себя пижаму и поворачиваясь на спину. Росио через силу улыбнулась и подошла к постели. Но, посмотрев на распростертую на простынях громадную тушу, почувствовала облегчение.

Выглянув в пустую шифровалку, он принял решение. На загрузку программы и поиск вируса уйдет минут пятнадцать. Скажи, что ничего нет, - прошептал .

Слова Сьюзан Флетчер о том, что ключ находится в Испании, показались ему обнадеживающими. Он бросил быстрый взгляд на Сьюзан, которая по-прежнему сидела на стуле, обхватив голову руками и целиком уйдя в. Фонтейн не мог понять, в чем дело, но, какими бы ни были причины ее состояния, выяснять это сейчас не было времени. - Нужно решать, сэр! - требовал Джабба.  - Немедленно.

Как и многие другие сотрудники АНБ, он использовал разработанную агентством программу Мозговой штурм - безопасный способ разыгрывать сценарий типа Что, если?. на защищенном от проникновения компьютере. Мозговой штурм был своего рода разведывательным экспериментом, который его создатели называли Симулятором причин и следствий. Сначала он предназначался для использования в ходе избирательных кампаний как способ создания в режиме реального времени моделей данной политической среды.

И в тот же миг ей открылась ужасающая правда: Грег Хейл вовсе не заперт внизу - он здесь, в Третьем узле. Он успел выскользнуть до того, как Стратмор захлопнул крышку люка, и ему хватило сил самому открыть двери. Сьюзан приходилось слышать, что сильный страх парализует тело, - теперь она в этом убедилась.

 Si, senor, - засмеявшись, ответила Мидж с подчеркнутым пуэрто-риканским акцентом и, подмигнув Бринкерхоффу, направилась к двойной двери директорского кабинета. Личный кабинет Лиланда Фонтейна ничем не походил на остальные помещения дирекции. В нем не было ни картин, ни мягкой мебели, ни фикусов в горшках, ни антикварных часов.

Джабба поднял брови. - Хорошо, это ничего не дает.

 У нас вирус. Затем раздался крик: - Нужно немедленно вызвать Джаббу. Послышались другие звуки, похожие на шум борьбы. ГЛАВА 55 - Ты уселся на мое место, осел.

Сумка, с которой она приехала, на дощатом полу посреди комнаты… ее белье на спинке стула эпохи королевы Анны, стоящего возле кровати. Вернулся ли Дэвид. Она помнила его тело, прижавшееся к ее телу, его нежные поцелуи. Неужели все это был сон. Сьюзан повернулась к тумбочке.

 - Сюрреализм. Я в плену абсурдного сна. Проснувшись утром в своей постели, Беккер заканчивал день тем, что ломился в гостиничный номер незнакомого человека в Испании в поисках какого-то магического кольца. Суровый голос Стратмора вернул его к действительности. Вы должны найти это кольцо.

В панике она сразу же представила себе самое худшее. Ей вспомнились мечты коммандера: черный ход в Цифровую крепость и величайший переворот в разведке, который он должен был вызвать. Она подумала о вирусе в главном банке данных, о его распавшемся браке, вспомнила этот странный кивок головы, которым он ее проводил, и, покачнувшись, ухватилась за перила. Коммандер.

Нуматака терпеть не мог вести дела подобным образом, он ненавидел, когда хозяином положения был кто-то. С самого начала его преследовала мысль, что звонки Северной Дакоты - это западня, попытка японских конкурентов выставить его дураком. Теперь его снова одолевали те же подозрения.

Наконец она остановилась, и дверь открылась. Покашливая, Сьюзан неуверенно шагнула в темный коридор с цементными стенами. Она оказалась в тоннеле, очень узком, с низким потолком.
