Question 1

what is the definition or description of: carcinoma in situ?

Accepted Answer

Not cancer: Human papilloma virus is a sexually transmitted virus. It can attack and change cells at the end if the birth canal. Simply put, if there is a small change, it is called mild dysplasia.Worsening, it becomes moderate and severe dysplasia. Carcinoma in situ is very severe dysplasia, with the next step being cancer. Stages are also called cin, cervical intraepithelial neoplasia, or inside the cell.

Question 2

whats the difference between carcinoma in situ and cin?

Accepted Answer

Since no one has: Answered in a week, i think it is because like me, they do not know what cin is. We all know that carcinoma in situ means the cancer is superficial, not invading through a structure, and generally conveying risk of becoming invasive cancer.  This is most prevalently used in breast cancer. However, i cannot contrast to cin. I do not know what that is.

Question 3

i was wondering are precancerious polyps carcinoma in situ?

Accepted Answer

Not necessarily: Most precancerous polyps of the colon are considered adenomas.  These can progress to contain areas of severe dysplasia and/or carcinoma in situ which mean that they are one step closer to becoming malignant.

Question 4

i was diagnosed with anal carcinoma in situ twice what are the chances that it will reoccure?

Accepted Answer

Unfortunately High: Anal carcinoma in situ is a rare pre-cancerous condition that often will recur.  It may be associated with HIV and is usually directly caused by hpv.  Sometimes close observation by anal "mapping" every 3-4 months is enough with small operations to remove any new lesions as needed. In other instances, treatment with imiquimod, laser therapy or radiation therapy might be recommended.

Question 5

hpv now sever/carcinoma in situ not sure if it spread yet, how to know?

Accepted Answer

If you know you: Have HPV, and now have dysphasia, time to visit Gyn Onc to discuss options if you would like to avoid hysterectomy now.

Question 6

what would confirm the diagnosis of carcinoma in situ of the large intestines?

Accepted Answer

Biopsy: A colonoscopic biopsy would be necessary to make the diagnosis of colon cancer. It is the gold standard. Good luck.

Question 7

i need to know what is treatment for extensive high grade ductile carcinoma in situ?

Accepted Answer

Excision and XRT: The standard treatment for high grade dcis is complete excision of the abnormal area(calcification and any palpaable tumor) followed by radiotherapy on recovery from surgery. It is best to then take tamoxifen as adjuvant therapy for 5 years.
Good luck.

Question 8

how are carcinoma in situ and benign neoplasm different?

Accepted Answer

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.

Question 9

is cervical carcinoma in situ considered cancer or pre cancer?

Accepted Answer

Pre- cancer: It is good to seek treatment from a gynecologist as it will require some form of local therapy to either excise it or burn it off with Laser or cryotherapy. if done well it can be easily eradicated.

Question 10

the decision was that i have lobular carcinoma in situ. what is it?

Accepted Answer

Also called lobular: Neoplasia...It forecasts that you will develop a breast cancer in either breast. Some used to do "mirror" biopsies. Others contemplate bilateral mastectomy. Lcis is a risk not a cancer, but the lobular invasive cancer can pose detection problems. Discuss this with a breast cancer team. I would watch very carefully. Lobular cancer makes up only 15% of invasive cancer.
