Carcinoma

What Is Carcinoma?

Carcinoma is any cancer that arises from epithelial cells. It is malignant by definition: carcinomas invade surrounding tissues and organs, and may spread to lymph nodes and distal sites (metastasis). Carcinoma in situ (CIS) is a pre-malignant condition, in which cytological signs of malignancy are present, but there is no histological evidence of invasion through the epithelial basement membrane.

Types of Carcinoma

Carcinoma, like all neoplasia, is classified by its histopathological appearance. Adenocarcinoma and squamous cell carcinoma, two common descriptive terms for tumours, reflect the fact that these cells may have glandular or squamous cell appearances respectively. Severely anaplastic tumours might be so undifferentiated that they do not have a distinct histological appearance.

Carcinoma Picture

Some of the most common carcinomas are: basal cell carcinoma, squamous cell carcinoma, renal cell carcinoma, small cell carcinoma, cervical carcinoma, hepatocellular carcinoma, ductal carcinoma, transitional cell carcinoma, adenoid cystic carcinoma, merkel cell carcinoma, neuroendocrine carcinoma, papillary carcinoma, bronchogenic carcinoma...

Staging

Sometimes a tumour is referred to by the presumptive organ of the primary (eg carcinoma of the prostate) or the putative cell of origin (hepatocellular carcinoma, renal cell carcinoma).

Lung Carcinoma: The Bad and the Worse

There are two major types of lung cancer. One is the Small Cell Lung Cancer (SCLC) mentioned in the previous paragraph. The other is Non-Small Cell Lung Cancer (NSCLC). Non-Small Cell Lung Cancer has three subtypes: Adenocarcinoma, Squamous Cell Carcinoma and Large Cell Undifferentiated Carcinoma. NSCLC is the least "serious" of the two types. In fact, if it is detected early, it is possible that it can be cured with surgery.

Breast Carcinoma 101

The most common type of breast cancer is ductal carcinoma, which begins in the cells of the ducts. Cancer that begins in the lobes or lobules is called lobular carcinoma and is more often found in both breasts than are other types of breast cancer.

Skin Carcinoma: Keep Your Skin Safe

The two most common types of skin cancer are basal cell carcinoma and squamous cell carcinoma which are usually curable. The third type, melanoma, is much more dangerous and one of the most common cancers in young adults.

Staging Colon Cancer

In Stage 0, the colon cancer is found in the innermost lining of the colon only. Stage 0 colorectal cancer is also called carcinoma in situ. In Stage I, the colon cancer has begun to spread, but is still in the inner lining of the colon or rectum. In Stage III, the colon cancer has spread to lymph nodes, but has not been carried to distant parts of the body. In Stage IV, the colon cancer has been carried through the lymph system to distant parts of the body.

Save Yourself From Lung Carcinoma

Three common types of non-small cell lung cancer are squamous cell carcinoma, adenocarcinoma and large cell carcinoma. Squamous cell carcinoma is the most common non-small cell lung cancer.Adenocarcinoma, the primary cause of this non-small cell lung cancer is still a challenge to medical experts. Thus, experts continue to study the major cause of this cancer.

Knowing the Difference between Squamous Cell Carcinoma and Basal Cell Carcinoma?

Basal Cell Carcinoma and Squamous Cell Cancers are the most common Non-melanoma skin cancers and they can appear in a variety of forms. Skin cancer cells are located at the base of the outer layer of the skin or cover the internal and external surfaces of the body. Most non melanoma skin cancers develop on sun-exposed areas of the body, like the face, ear, neck, lips, and the backs of the hands. Each type, has varied growing rates and characteristics, if untreated they can spread to other parts of the body.

Renal cell carcinoma

Renal cell carcinoma, also known by the eponym Grawitz tumor, is the most common form of kidney cancer arising from the renal tubule. It is the most common type of kidney cancer in adults. Initial therapy is with surgery. It is notoriously resistant to radiation therapy and chemotherapy, although some cases respond to immunotherapy.

Lung adenocarcinoma

Adenocarcinoma is the most common type of lung cancer, accounting for 30-35% of all cases.Over the past 30 years, the frequency of adenocarcinomas has increased, while, squamous cell carcinomas have decreased.This is believed to be due to a true change in the biological occurence and not a change in criteria for diagnosis.Adenocarcinoma is the most common cause of lung cancer in women and nonsmokers and is the most common cell type associated with lung scarring from other causes ("scar carcinoma").
