What are the differences between melanoma and squamous cell carcinoma?

What are the differences between melanoma and squamous cell carcinoma?

Different cell types: Melanomas originate from pigment producing cells called melanocytes, whereas squamous cell carcinomas from squamous cells in the skin. They appear different clinically. The former most frequently have irregular borders and many shades of brown, whereas the latter is often red scaly crusty plaques. However, rarely melanomas can loose their pigment and look like squamous cell ca. ...Read more

Cancer (Definition)

Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more

What is the difference between "malignant melanoma" and "basal cell carcinoma"?

What is the difference between "malignant melanoma" and "basal cell carcinoma"?

Types of cancer: Malignant melanoma is a type of cancer that originates from the melanocytes. It often travels to distant locations in the body and is the deadliest form of skin cancer. Basal cell carcinoma rarely travels to other parts of the body, but will recur locally if not treated appropriately. ...Read more

What are the differences between sarcoma and carcinoma cancers?

What are the differences between sarcoma and carcinoma cancers?

Derivation: sarcomas arise from supportive tissues of the body. They are found in and derived from muscle, fibrous tissue and fascia, fat, nerve, blood vessel and bone. Spread is to liver and lung. Carcinomas arise from secretory and epithelial membrane spreading first to regional nodes as seen with breast, colon and lung. They respond differently to chemo. ...Read more

What is the difference between squamous cell carcinoma and basal cell carcinoma?

What is  the difference between squamous cell carcinoma and basal cell carcinoma?

Different origins: Skin cancers are named for the type of skin cell that they develop from. A basal cell is generally a less dangerous tumor unless it is near an opening such as the nose, eye or ear. The squamous cell is more serious, requires a more aggressive surgical removal, and will sometimes spread inside the body (metastasize). ...Read more

What is the difference between: basal cell carcinoma epithelioma, squamous cell carcinoma, and melanoma?

Skin cancer: The difference between basal cell carcinoma, squamous cell carcinoma, and melanoma has to do with how the skin cancer cells appear under the microscope as well as how they behave. Therefore it is important that they be diagnosed and treated as quickly as possible by a healthcare professional who specializes in this area. ...Read more

Non-small cell carcinoma and small cell carcinoma. What is the difference?

Non-small cell carcinoma and small cell carcinoma.  What is the difference?

Small cell. all else: Small cell cancer of the lung is a specific kind of cancer that has uniform, small cells. Non small cell cancer is the term for all other cancers that are in the lung, like adenocarcinoma, squamous cell cancer, and large cell cancer. These are grouped this way due to treatment approach. Small cell presents as widely disseminated and gets chemo., while non small cell is localized, gets surgery. ...Read more

How to differentiate between the stages of squamous cell carcinoma under the microscope?

How to differentiate between the stages of squamous cell carcinoma under the microscope?

Cant stage: When one examines a biopsy under the microscope, the pathologist will grade the tumor into high and low grade lesions depending on loss of characteristic structure of the normal cell. Stage depends on clinical evaluation in terms of size and spread from the primary site. ...Read more

How are carcinoma in situ and benign neoplasm different?

Good question: And difficult to tell sometimes. The most straightforward way to put it is that a benign neoplasm will never turn into an invasive malignancy within your lifetime. Cis will eventually turn into one. But, because we don't live forever, cis might not turn into a malignancy during one's lifetime anyway. Pathologists can usually, but not always, tell the difference by microscopic cell exam. ...Read more

What is the difference between small cell and non-small cell cancers?

What is the difference between small cell and non-small cell cancers?

SCLC more aggressive: Under a microscope, small cell lung cancer (SCLC) looks different from other types of lung cancer (non-SCLC, or NSCLC). SCLC tends to grow more rapidly and metastasize more. But it responds better to chemotherapy and radiation therapy than does NSCLC. Surgery is rarely indicated for SCLC. ...Read more

What are stages of squamous cell carcinoma?

What are stages of squamous cell carcinoma?

Differentiated: The pathology report will desribe well, moderate or poorly differentiated. Well differentiated is less advanced. It will also describe depth on invasion and whether nerves are involved. An evaluation of lymph nodes is done to confirm squamous cell is localized to skin. In advanced cases it will have spread requiring surgery followed by radiation, and possible chemotherapy. ...Read more

What are the symptoms of basal cell carcinoma?

What are the symptoms of basal cell carcinoma?

Symptoms: There are few symptoms of a basal cell carcinoma. Occasionally they may bleed but usually the hallmark of a basal cell carcinoma is a skin lesion with raisd pearly borders and ulceration or a sore area in the center. ...Read more

What is the difference between neoplasm, adenoma, and carcinoma?

What is the difference between neoplasm, adenoma, and carcinoma?

Different tumors: Neoplasm = new growth. Neoplasms can be benign or malignant. An adenoma is a benign neoplasm. A carcinoma is a malignant neoplasm. Hope this helps. ...Read more

What are the tests for basal cell carcinoma?

What are the tests for basal cell carcinoma?

Biopsy: The only test for basal cell cancer is a biopsy of the lesion. Doctors are looking for lesions that are red, ulcerated, slow to heal or irritated as a possible sign for basal cell carcinoma. There is no blood test. ...Read more

What is the difference between malignant and benign cancers?

What is the difference between malignant and benign cancers?

Cancer: There are benign tumors (grow but don't spread) and malignant tumors (grow and spread to other parts). These last ones are cancers. There is no such thing as a benign cancer even though some behave less aggressively than others. ...Read more

What is the difference between sarcoma and carcinoma?

What is the difference between sarcoma and carcinoma?

Different cancers: Sarcomas are very rare cancers that arise from bone, muscle, nerves, blood vessels or other connective tissues. Carcinomas are very common cancers that tend form glands. Most common examples are breast cancer, lung cancer, colon cancer, prostate cancer and renal (kidney) cancer, among others. ...Read more

What is the difference between carcinoma and sarcoma?

Cell of origin: Both are malignancies. Carcinoma arises from the lining tissues- both on the outside (e.g. Skin) and inside(intestine). Sarcomas from the mesenchyme- the tissues inside the lining. ...Read more

Skin Cancer (Definition)

A condition in which some element of your skin--which is one of the most complex organs in the body--degenerates into cancer. The three most common types of skin cancer are: basal cell, squamous cell, and melanoma which occur in that order and degree of aggressiveness. Although heredity plays a major role, sun exposure and tobacco use and ...Read more

Squamous Cell Cancer (Definition)

By definition, these mimic the squamous epithelial surfaces of the body that provide protection. Keratin pearls, prominent desmosomes, apoptosis of individual cells, staining for the distinctive molecules in these surfaces all help ...Read more
