Adenocarcinoma is a type of cancer that originates in glandular tissues, formed by cells capable of secreting substances into the organism. This type of malignant tumor can develop in different body organs, such as the prostate, intestine, lungs, breasts, uterus and pancreas.
In a general way, adenocarcinomas are cancers that are difficult to remove by surgery, with rapid growth and aggressive nature, as they have the ability to generate metastasis, however, there are specific characteristics according to each type and stage (stage) in which find
Some of the main examples include:
1. Prostate adenocarcinoma
It is cancer that appears in the glandular cells of the prostate and is more common in men over 65 years of age. In spite of growing slowly and gradually, some types can have rapid, aggressive growth and easily spread by other organs, generating metastasis.
Prostate adenocarcinoma can be divided into other subtypes, since adenocarcinoma is the most common. See how to identify and treat prostate cancer.
2. Lung adenocarcinoma
Pulmonary adenocarcinoma is cancer that affects the glandular cells of the lungs. It is one of the most common types of lung cancer, representing about 30% of cases. This type of tumor is usually aggressive, which is why it is important that your bone treatment is started as soon as possible once it has been identified. Learn more about symptoms that indicate lung cancer and what to do to treat it.
3. Gastric adenocarcinoma
It is the malignant tumor that appears in the cells of the stomach and represents 95% of the tumors that affect this organ, being more common in people older than 50 years.
The symptoms that indicate this tumor include abdominal pain, weight loss, nausea and difficulties in swallowing or digesting food. See more details on the main symptoms of stomach cancer.
4. Intestinal adenocarcinoma
95% of colorectal cancer cases are caused by adenocarcinomas, which are one of the most common types of cancer in the population. Generally, this type of tumor responds twice to treatment, especially if it is discovered in an early stage and other organs of the body are reached, making it very important to carry out screening tests recommended by doctors, such as when the blood test is hidden or the colonoscopy is performed. , for example, especially for people with family backgrounds, risk factors or older than 50 years.

5. Pancreas adenocarcinoma
The most common type of pancreas cancer is adenocarcinoma. Generally, they are aggressive tumors, many times they grow without causing symptoms and when they are discovered when they are at an advanced stage.
Know what are the main symptoms of pancreas cancer.
6. Breast adenocarcinoma
Breast cancer is largely due to adenocarcinomas. This tumor must be detected early in order to obtain better results and better chances of cure during treatment, so it is important that screenings are carried out with consultations with a gynecologist or a breast specialist, mammograms and self-examination.

Classification of adenocarcinoma
One of the ways to classify a cancer is by type of growth, which could be:
- adenocarcinoma in situ: it is the first stage, in which the cancer is however located in the layer of tissue where it developed and in the hubo invasion for deeper layers and therefore, it is easier to cure;
- invasive adenocarcinoma: arises when cancer cells reach other tissue layers, being able to reach external organs or propagate through the blood stream, causing metastasis;
- Bien differentiated adenocarcinoma: when the cancer receives this classification, it indicates that they are cancer cells that are similar to the original tissue and with slower growth;
- poorly differentiated adenocarcinoma: indicates that the tumor cells have very different characteristics from the original tissue and that may indicate a greater potential for malignancy and difficult treatment;
- Moderately differentiated adenocarcinoma: it is in an intermediary level between el bien and el poco differentiated.
Generally, to identify the classification of cancer, it is necessary to perform a biopsy of the tumor tissue, capable of microscopically detecting these characteristics.
How is the treatment performed?
The treatment for adenocarcinoma varies according to the location, type and classification of the tumor, generally, the treatment options include: radiotherapy, chemotherapy and tumor extirpation through surgery.
The adenocarcinomas can be aggressive and difficult to treat, and therefore, the prognosis is very individualized. It is very important to talk to the doctor about the options, their consequences and their benefits before deciding when and where to start the treatment.
