What is the definition of adenocarcinoma?

Question

My sister-n-law was first diagnosed with ovarian cancer and then the doctors mentioned the word "adenocarcinoma" what does this mean?

Answer 1

Adeno=gland
carcino=cancerous
oma=tumor
adenocarcinoma=means cancerous tumor of a gland

Answer 2

Acdenocarcinoma- oncology, tumour> A form of cancer that involves cells from the lining of the walls of many different organs of the body. Breast cancer is a type of adenocarcinoma.

Answer 3

Adenocarcinoma is a cancer that develops in the lining of an organ.

Answer 4

in a medical terms: adenocarcinoma means a malignant neoplasm of the epithelial cells in gladular or a gland like pattern.

it's one of the most commen type of tumer in the body, it can exist almost everywhere; such as the case in an ovarian cancer.

it is only type of tissue classification, it has nothing to do with staging the tumer. in another words; the term has nothing to do with the prognossis or survival of the patient.

wishing her all the best...

Answer 5

Adenocarcinoma is a form of carcinoma that originates in glandular tissue. To be classified as adenocarcinoma, the cells don't necessarily need to be part of a gland, as long as they have secretory properties. This form of carcinoma can occur in some higher mammals, including humans[1].

It can first present as an adenoma (a glandular tumor that is benign.)

It is frequently associated with cancers such as:

breast cancer
colon cancer
lung cancer
prostate cancer
stomach cancer
pancreatic cancer (75-96% are Ductal cell adenocarcinoma


In medicine, 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.

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 (undifferentiated carcinoma).

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).

[edit]
Types of carcinoma
Adenocarcinoma is a malignant tumour originating in the epithelial cells of glandular tissue and forming glandular structures. This is a common in the lung forming 30-40% of all lung carcinomas, found peripherally, arising from goblet cells or type II pneumocytes.
Squamous cell carcinoma due to squamous metaplasia. This accounts for 20-30% of lung tumours and is usually hilar in origin.
Small cell carcinoma is almost certainly due to smoking. These metastasise early, and may secrete ADH (lowering patient sodium concentration).
Large cell undifferentiated carcinomas account for 10-15% of lung neoplasms. These are aggressive and difficult to recognise due to the undifferentiated nature. These are most commonly central in the lung.
Sinonasal undifferentiated carcinoma
[edit]
Staging
The staging of cancers is the extent of spread of the neoplasm. Grading is the system used to record the tumours degree of differentiation from the parent tissue. A high grade shows little differentiation and the prognosis is therefore poor.

Carcinomas, like all cancers, are staged according to the extent of disease. The UICC/AJCC TNM system is often used, however for some common tumours, classic staging methods (such as the Dukes classification for colon cancer) are still used.

Answer 6

Not much else really.

Impressive without pasting a bunch of garbage from any old med site don't you think.

Cancer cells are only allowed to exist because of a few missing complex carbohydrates, which results in the transfer of biological data to fail. For goodness sake, this is four time Nobel Prize winning science and has been about for more than a decade. 350,000 scientific papers written in its acclaim too, and pier reviewed.

What else? Oh, it didn't kill any rats in the mandatory LD50 tests.

Doctors will 'mention' all sorts of garbage and never actually do anything much for you when you have cancer. take my advise, look else where.

Good luck.

Answer 7

Why do no longer you purely google it like I purely did? Adenocarcinoma is a maximum cancers that originates in glandular tissue. This tissue is likewise area of a much bigger tissue class straightforward as epithelial tissue. Epithelial tissue incorporates pores and skin, glands and a type of alternative tissue that strains the cavities and organs of the physique. Epithelium is derived embryologically from ectoderm, endoderm and mesoderm. To be labeled as adenocarcinoma, the cells do no longer unavoidably might desire to affix a gland, as long as they have secretory residences. this style of carcinoma can take place in some larger mammals, which contain people.[

Answer 8

It's a form of cancer that involves cells from the lining of the walls of many different organs of the body.

Answer 9

Oh dear,I'm so sorry to hear about this.
Adenocarcinoma means malignant tumour of glandular epithelium.
Gross picture:
cauliflower mass projecting into the lumen.
-constricting diffuse infiltrating mass.
-or malignant ulcer.
By microscope:
complex irregular glandular structures which are lined by one or more layers of epithelial cells which are irregularly arranged.The nuclei of the individual cells are enlarged & may show mitotic figures.The neoplastic glands infiltrate the underlying structures & cause distant metastasis.
It has 3 grades differing in severity & response to ttt.
So I hope it's in early stage & it's well differentiated & it will response.
& I'll pray & ask Allah to help her .
I wish I could help.

Answer 10

WELL, CARCINOMA MEANS CANCER, BUT I CANNOT HELP YOU WITH THE ''ADENO'' PART. TRY GOOGLING THE WORD.......
