Neoplasma: Definition and Divisions (Part Two)

1. Lipomas-these growths originate from fat cells and are the most common type of non-cancerous neoplasm which are present in adults, which often occurs in the back, arms, shoulders, or neck. They commonly grow slowly and are movable and quite soft to the touch.

Pre-cancerous or Pre-malignant

Precancerous neoplasms denote masses which have yet to be cancerous, but have the potential to do so if they are not well treated. Oftentimes, cells may even undergo changes which eventually go away by themselves. But, other cells pass on mutations and the new ones will slowly become even more abnormal until they finally become cancerous. The different traits of premalignant changes which can arise are pointed below.

1. Hyperplasia-this constitutes an abnormal increase in the number of occurring cells. This is not commonly precancerous, yet some cases of hyperplasia are.
2. Atypia-cells that are observed under microscope look a bit typical. This can be cased by inflammation, sometimes, and healing and my go away once the inflammation cease or the body has healed.
3. Metaplasia-cells that are observed under the microscope that appear normal, yet are not the cell type that are usually found in that bodily tissue or area. Metaplasia is not commonly precancerous, yet some cases are.
4. Dysplasia-cells possess an abnormal appearance under microscope and appear disorganized. Dysplasia refers to a precancerous condition in the majority of cases and people with dysplasia are commonly checked on a regular basis so that required treatment can be initiated if cells change become aggressively severe.

Malignant Neoplasm

This terms refers to neoplasm which has been cancerous, as described by the following typical features: the capacity to invade other tissues, abnormal cell growth, and the capacity to spread to distant organs via blood vessels or the lymphatic channels or metastasis.

If untreated, these malignant or cancerous neoplasms will continue to quickly divide and multiply in uncontrollable and abnormal fashion. The tumor will get larger and may eventually invade the surrounding areas or tissues and even spread to other distant parts of the body vie the blood or lymphatic system. In case a lot of organs or vital ones such as the liver or brain has been extensively damaged by the cells, then death is likely to occur. The treatments that are available for treating malignant cancer comprise surgery, chemotherapy, and also radiotherapy. But, once metastasis has taken place, the patient’s prognosis will be quite poor that treating multiple areas affected is not possible.

The type of cancer that a person has and where in his body it grew are the predominant factors which impact where the cancer will spread to. The extent of metastasis during diagnosis is referred to as the cancer stage and lots of cancer are categorized using staging system which ranges from 0 to 4. Knowing the cancer stage and where the cell may spread to the next stage will help doctor to extrapolate disease course and decide on the most effective treatment plan. As such, it is highly important that everyone is aware of the early signs of neoplasm.
