Esophageal Cancer Stages

Cancer » Esophageal Cancer » Esophageal Cancer Stages

In every individual, the esophagus is situated in the chest. The esophagus is an organ that is a tube which is hollow and muscular in structure. The esophagus works by taking forward the food to the stomach from a person's mouth. An esophagus is a part of the digestive tract. An esophagus is approximately 10 inches long in length. The esophagus cancer has been divided into two types. The types are:

  • Squamous carcinoma in the cell of the esophagus: It is the most frequently occurring type of esophagus cancer. It forms on the upper layer of the esophagus of an individual. A study shows that this type of esophagus cancer has become uncommon among the American people.
  • Adenocarcinoma in esophagus: Such a type of esophagus cancer usually occurs in the lower layers of the esophagus, that is somewhere near the stomach of an individual. It is supposed to be very common among the esophageal cancer patients in the USA.

Esophageal cancer stages:

The staging of the esophageal cancer is done in a certain way in order to recognize the exact impact that the cancer has caused in the patient at the current stage or where the cancer has reached so far. The esophageal cancer stages can be described in the way mentioned below.

  • Stage 0: This stage is also called as the 'Carcinoma in situ' in many of the cancers. In the esophagus 0 stage cancer, some cells that are very uncommon or abnormal are seen to been present in the esophagus tissues layer which is the innermost one. There are high possibilities of such abnormal cells converting into the cancer.

  • Stage 1: The stage one denotes that the cancer has just completed its formation and is spreading further of the esophagus tissues innermost layer. It means the cancer has spread in the esophagus wall through the wall tissues next layer.

  • Stage 2: In the second stage of esophageal cancer, further division of the stage is done in order to know where exactly the cancer has moved. The further staging is;

    • Stage 2 A: In this stage, it is seen that the cancer has moved upto the esophagus' outer wall or to the esophagus muscle layer.
    • Stage 2 B: In this stage, it is believed that the esophageal cancer must have spread to the lymph nodes which are nearby the esophagus and the esophagus three layers.

  • Stage 3: The esophagus cancer stage can be severe as the cancer must have spread to the lymph nodes or the tissues which are located near the esophagus and must have spread to the esophagus outer wall as well.

  • Stage 4: The stage 4 of the esophageal cancer also divides further into 2 stages depending on the place where the cancer has spread. The further stages in the 4th stage are:

    • Stage 4 A: The esophageal cancer at the 4 A stage denotes that the cancer has spread to the lymph nodes which are at a distance or are nearby from the esophagus.
    • Stage 4 B: It is the most invasive stage where the cancer either spreads to the other body parts or the lymph nodes that are distantly located.

The esophageal cancer staging helps the patients as well as the doctor to exactly understand the current location as well as the danger for the patient from the cancer. The staging decides how invasive the cancer has become in the patient's body and what esophageal treatment or cure measures should be taken.
