Question 1

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 2

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 3

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 4

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 5

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 6

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 7

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.

Question 8

when doctors say ductal carcinoma in situ, what does "in situ" mean?

Accepted Answer

"in place": Ductal carcinoma in situ (DCIS) of the breast is a breast cancer which has started in the ducts of milk glands (as most breast cancers do) but not yet invaded beyond that into the fat of the breast.  Untreated, it has a high likelihood of becoming invasive breast cancer, a potentially fatal disease.  Treated DCIS has a high cure rate.  Some with DCIS benefit from taking med to prevent  2nd cancer.

Question 9

how long does it take to go from carcinoma in situ to cervical cancer?

Accepted Answer

Not all invasive: Cancers start in situ, and not all in situ cancers ultimately invade...But a lot do.  So, there is no timetable of when that you can rely on.  It is reasonable to take care of in situ when you find it, rather than trust an unreliable actor to behave itself the way you might like.

Question 10

what treatments can you get for ductal carcinoma in situ?

Accepted Answer

More info needed: Surgery, radiation, hormonal pill. More info needed on size and extent of disease.
