Stage Of Breast Cancer
1 .- Stage 0
Noninvasive breast cancer or in situ.
a) Ductal carcinoma in situ (DCIS): Cancer cells are located within a duct, there is no invasion of surrounding fatty tissue.
b) Lobular carcinoma in situ (LCIS): The atypical cells grow inside the milk-producing glands, and do not penetrate through the walls of the lobe.
2 .- Stage I
The tumor is less than 2 centimeters in diameter. Has not spread beyond the breast.
3 .- Stage II
It is divided into IIA and IIB.
a) Stage IIA. It includes three categories: non-palpable tumor with positive lymph nodes but mobile, not fixed to each other, tumor less than or equal to 2 cm in greatest diameter with positive axillary nodes and tumors moving between 2 and 5 cm with negative axillary nodes.
b) Stage IIB. Two modes: Tumors between 2 and 5 cm in greatest diameter, axillary node-positive phones, tumors larger than 5 cm in greatest diameter, with negative lymph nodes in the armpit.
4 .- Stage III
This stage is divided into IIIA and IIIB:
a) Stage IIIA. They have the following modalities: non-palpable tumors, tumor diameter greater or less than 2 cm and tumors between 2 and 5 centimeters, if they have positive lymph nodes, fixed to each other or that have invaded other structures in the armpit. O tumors larger than 5 cm in greatest diameter with any positive node in the armpit.
b) Stage IIIB: Breast cancer of any size that has spread to the chest wall, skin of the breast or chest wall or skin and inflammatory carcinoma of the breast. Or any size tumor with positive nodes in the internal mammary tumor on the same side.
5 .- Stage IV
Cancer regardless of its size, has spread (metastasized) to distant organs such as bones, lungs or
Anal Cancer
Anal cancer is often curable. The three major prognostic factors are site, size and differentiation.
Cancer of the anus is a rare malignancy, representing only a small percentage (4%) of all cancers of the lower digestive tract
In general, the risk of anal cancer is increasing, and there is evidence that individuals with human papillomavirus and gay men in particular are at increased risk of autism. Read the rest of this entry »
Cancer in Pet Animals
Cancer is common in pet animals and the incidence increases with age. It causes about half of the deaths of pets over 10 years of age. Dogs get cancer at roughly the same rate as humans, while cats get fewer cancers.
Diagnosis
Strong circumstantial evidence of cancer can be achieved through x-rays, blood tests, ultrasonography, physical examination and medical history. Read the rest of this entry »

The Probable Etiology Of Pancreatic Cancer
If you remember a few months, and if I do, around here we were talking about a man, named Ferdinand and ex-worker Inquidesa in Huesca, who claimed her cancer was recognized as an occupational disease of the pancreas.
In the first post by February, a servant claimed that chlorine and pancreatic cancer are not related … it’s true. But in these Dr. Sanz told me, he knew first hand one of the experts Dr. Porta of Barcelona, that the compound they were talking about was not the only organ-chlorine, chlorine … and there published the second post correcting … for certain is that certain organ-chlorine (such as some insecticides that quoted in the first inning) are associated with pancreatic cancer.

Antibodies VS Cancer
Possible treatment with antibodies that could boost the immune system to help fight some cancers. The treatment showed a significantly higher survival neuroblastoma, a type of childhood cancer – in laboratory tests, and they expect to ever be used to treat children with this disease.
The antibodies did not work so well with more aggressive tumors, but researchers then one of them accompanied with a peptide, a protein fragment-specific, and together they destroyed between 40 and 60 percent of these tumors. Read the rest of this entry »
Renal Cell Carcinoma
Formerly known as hyper-nephroma, renal cell carcinoma or Grawitz tumor is a carcinoma that originates in the renal tubular epithelial cells. In order of frequency is the tenth malignancy in males and 14th among women, accounting for 2% of malignancies and is more common in men than in women, with a ratio 2 to 1.

Types of Brain Cancer
Brain Cancer Is the growth of cancer cells in the tissues of the brain can destroy brain cells and also cause damage to cells by inflammation and compression to tumor growth and can cause cerebral edema.
TUMORS
* Astrocytomas: originate in cells called astrocytes that vary in degree of malignancy.
* Oligodendroglial tumors originate in the brain cells oligodendrocytes. Read the rest of this entry »

An Anatomy Lesson
Lips, teeth, gums, buccal mucosa (inner lining of the lips and cheeks), the floor of the 
mouth, palate, and also the small area behind the wisdom teeth. All these areas are those that make up the oral cavity, next to the pharynx (posterior third of the tongue and throat, and tonsils) are the regions that are affected by malignant cells. Moreover, between the throat and stomach, the tube through which pass, among other substances, drink and food, is the esophagus. It is located just immediately behind the trachea and an adult has a length of around 25 centimeters. Read the rest of this entry »
