What are squamous cell carcinoma, basal cell carcinoma, and melanoma?

What are squamous cell carcinoma, basal cell carcinoma, and melanoma?

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. Squamous cell carcinoma rarely travels to other parts of the body. ...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

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

Non-healing ulcer: Basal cell carcinoma may present as an indolent, non-healing ulcer with spread to contiguous tissues. There may be nodules, pigment changes, bleeding and tissue destruction. ...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

What distinguishes cancer cells from the cells of benign neoplasms?

What distinguishes cancer cells from the cells of benign neoplasms?

Disordered growth: Benign tumors grow locally and do not spread. Under the microscope, the cells look like the gland they are from and they are not invading. Cancer cells have disordered growth, frequently do not look like the originating gland and show invasion. ...Read more

What is squamous cell vs basal cell skin cancer?

What is squamous cell vs basal cell skin cancer?

Different growth: Basal cell skin cancers often grow deeper and more destructive when left untreated causing large ulcerated areas. Squamous carcinomas more often spread radially and have a higher risk of spread to other organs if left untreated. ...Read more

Are squamous cell carcinomas indicitive of other cancers present in the body?

Are squamous cell carcinomas indicitive of other cancers present in the body?

No: You may be thinking of the sign of leser-trelat, in which numerous seborrheic keratoses pop up all-of-a-sudden; there's often a hidden colon cancer. These are a different skin lesion. ...Read more

What causes squarmis cell carcinoma?

What causes squarmis cell carcinoma?

Depends on location: The most common form of squamous cell carcinoma (scc) occurs on skin, with sun damage being the leading cause. Scc can also occur in the esophagus, lung, oral cavity, and anal canal. Prolonged exposure to irritants such as smoking and chewing tobacco can lead to increased risk of scc in the lung and oral cavity. A certain type of virus (human papillomavirus) can also increase the risk of scc. ...Read more

Which distinguishes cancer cells from the cells of benign neoplasms?

Genome destabilized: The key to cancer is that enough mutations have accumulated to render the genome itself unstable. Eventually a clone will acquire the ability to invade and spread. We can pick this up using molecular biology techniques. They also look different, but it takes a pathologist several years to learn to tell all the subtleties. ...Read more

Is a squamous cell something that forms squamous cell carcinoma?

Not necessarily: Squamous cells are normal constituents of skin and some of the other linings, e.g., vagina. Squamous cells per se do not give rise to any cancer. Some cancer have squamous cell features. ...Read more

Is squamos cell carcinoma of tonsils cureable?

Is squamos cell carcinoma of tonsils cureable?

Yes: It may be curable but you will need and extensive work up and close follow up with your otolaryngology surgeon (ent). Depending on the extent of cancer treatment may consist of any combination of surgery, radiation, and chemotherapy. Maintaining your nutrition and mental health during this time would be very important as well. ...Read more

What are effects of surgical excision of basal cell carcinoma?

What are effects of surgical excision of basal cell carcinoma?

Usually minimal: Assuming that the cancer is not very large most basal cells can be removed with minimal scarring. Using excisions along natural skin lines and using small suture for closure can minimize cosmetic defects. ...Read more

Invasive non keratinizing squamous cell carcinoma tongue showing nests of malignant squamous cells grade 3 prognosis?

Can be cured: If no nodes palpable and lesion localized, RT chemo can reduce size and position site for curative resection. Partial glossectomy after initial therapy. If larger and not responsive to chemo, Ive used hight dose MTX with citrovorum factor over 12 hrs. Most effective in presence of nodal disease Basic chemo is Platinum/Taxol + RT ...Read more

What's the chromosome number of infiltrating ductal carcinoma?

What's the chromosome number of infiltrating ductal carcinoma?

Depends on grade: The level of chromosomal aberrations in infiltrating ductal carcinoma is correlated with the grade of the cancer cells. "grade" means the microscopic appearance and corresponds with how closely the cancer cells try to form normal breast structures. High grade or poorly differentiated infiltrating ductal carcinomas tend to have more chromosomal abnormalities than non-high grade carcinomas. ...Read more

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
