This stage is usually a small cancer or tumor that has not grown deeply into nearby tissues. It also has not spread to the lymph nodes or other parts of the body. It is often called early-stage cancer. In general, these 2 stages indicate larger cancers or tumors that have grown more deeply into nearby tissue. They may have also spread to lymph nodes but not to other parts of the body. Stage IV. This stage means that the cancer has spread to other organs or parts of the body.
It may also be called advanced or metastatic cancer. The stage of a cancer does not change over time. If the cancer comes back or spreads to another part of the body, the more recent information about the size and spread of the cancer is added to the original stage. This process uses the same staging system described above.
Usually some of the same tests that were done when the cancer was first diagnosed will be repeated. After this, the doctor may assign the cancer a new stage. However, this is not common. The TNM system is mainly used to describe cancers that form solid tumors, such as breast, colon, and lung cancers. However, doctors use other staging systems to classify other types of cancer, such as:.
Central nervous system tumors brain tumors. Because cancerous brain tumors do not normally spread outside the brain and spinal cord, only the "T" description of the TNM system applies. Currently, no single staging system exists for central nervous system tumors.

Doctors stage most childhood cancers separately according to other staging systems that are often specific to the type of cancer. Oversight of one cell can mean mistaging and lead to serious, unexpected spread of cancer.
If cancerous cells present in the lymph node happen not to be present in the slices of tissue viewed, incorrect staging and improper treatment can result.
Emotional neglect is linked to advanced cancer stages. New, highly sensitive methods of staging are in development. For example, the mRNA for GCC guanylyl cyclase c , present only in the luminal aspect of intestinal epithelium , can be identified using molecular screening RT-PCR with a high degree of sensitivity and exactitude.
Presence of GCC in any other tissue of the body represents colorectal metaplasia. Researchers hope that staging with this level of precision will lead to more appropriate treatment and better prognosis. Furthermore, researchers hope that this same technique can be applied to other tissue-specific proteins. Staging systems are specific for each type of cancer e. Although competing staging systems still exist for some types of cancer, the universally-accepted staging system is that of the UICC , which has the same definitions of individual categories as the AJCC.
For solid tumors, TNM is by far the most commonly used system, but it has been adapted for some conditions. Within the TNM system, a cancer may also be designated as recurrent, meaning that it has appeared again after being in remission or after all visible tumor has been eliminated. Recurrence can either be local, meaning that it appears in the same location as the original, or distant, meaning that it appears in a different part of the body.
Stage migration is a change in the distribution of stages in a particular cancer population, induced by either a change in the staging system itself or else a change in technology which allows more sensitive detection of tumor spread and therefore more sensitivity in detecting spread of disease e. Stage migration can lead to curious statistical phenomena for example, the Will Rogers phenomenon.

The stage of your cancer helps your doctor to decide which treatment you need. Treatment also depends on:. The treatment for small cell lung cancer is different to the treatment for non small cell lung cancer.
After you finish treatment, you might have radiotherapy to your head. This treatment is called prophylactic cranial radiotherapy PCR. You have this because it is quite common for small cell lung cancer to spread to the brain.
The radiotherapy aims to kill any cancer cells that may have already spread to the brain but are still too small to see on scans.Mar 31, · “There is a stage four – just look at the UK and Europe – total lockdown,” said public policy expert and former senior Howard Government adviser Terry Barnes. “The list of essential businesses or jobs gets really tight. Effectively it’s martial law without martial law.
