Describe the three different types of malignant tumors?

What are the three types of malignant tumors? What are their characteristics?
Carcinoma, sarcoma, leukemia, and lymphoma . . there are four types . . five if you count brain tumors.
You can look up the characteristics yourself since this sounds like a homework question.

Is it possible to tell if a tumour is benign or malignant by sight and touch?

---

I know someone who is getting checked to see if their tumour is benign or malignant tomorrow and they are very worried at the moment about it being cancerous or not. Is it possible to make a rough guess by touch and/or sight or the tumour? [It's on the shoulder]
A doctor can tell if something is more or less likely to be malignant but can never be 100% sure without biopsy results.  (+ info)

What is the best treatment for vaginal malignant melanoma stage 2c ?

---

i have a vaginal malignant melanoma. the tumor is 2.5 cm. with ulceration. I made a surgery where ovaries, uterus, the posterior wall of the vagian and the rectum where removed. my doctor said i am of high risk of recurrence. he told me there is no treatment available now except interferon and he is not really sure about its proficiency. the recommended dose he suggested is 3 million to be injected under the skin three times a week. Please help me if there are other treatments and ,if not, is the 3 million interferon dose effective or not. i did the surgery two months ago. no lymph nodes were affected. waiting for your replies. thanks everyone.
I'd go for the interferon therapy for at least a year or longer. I'd want to get started asap. Interferon is a very strong drug and can make you depressed but it has incredible anti-tumor potential plus it is your best option for avoiding another melanoma. 3million units is a rather low dose for melanoma. I'd ask about doing 5 or 10 million units 3X week. Cost will be the same for the higher dosage. I hope you have good drug insurance as interferon is very expensive. If you do not, I'd look into the Patient Assistance programs and maybe you can receive the meds for no cost if you have a very limited income. Your Dr should have already gone through all this with you. Be aggressive with taking care of yourself and in seeking out additional treatment. Remember the squeaky wheel gets the grease - or in this case the interferon.

The advice about starting an antidepressant at the same time as the interferon is good. Also know that interferon side effects can be minimized by taking ibuprofen or Tylenol a couple hours after each interferon injection. Expect to be tired and need to sleep a lot. Give yourself permission to rest and take things easy. In some people the side effects decrease as time goes by. Since you had no nodal involvement you have a chance to be healed and even if the interferon treatment is very difficult, being healed has a great upside compared to doing nothing to prevent a second melanoma or recurrence. good luck

How does a benign tumor differ from a malignant tumor?

---

I know that benign isn't cancerous and malignant is... but I want to know, if there a difference in growth, feeling, look??? I have a tumor on my lip and a lump on my cervix... I'm so worry, I am having the one on my lip removed next month, but before then, is there any way to tell the difference?? Please, I'm only 18 & so worried!
When they remove the tumour they will do a biopsy which means they will examine the tumour for cancer cells. That is the only way to tell if it is cancerous. Having said that I would say that if your doctor really thought that you had cancer he would not be waiting a month to do the surgery. You would be on a emergency list to have it done now. I had a friend who
is much older than you and she found a lump on her breast
She called her doctor and he saw her that day. He was
sure it was cancer. She saw the surgeon the next day and had the biopsy and the day after that her breast was removed. I was away for a long weekend and came back to this. It was done on Friday Saturday and Sunday. Imagine
how shocked I was when I called her on Monday and found out from her daughter what had happened. If they seriously
think something is wrong they can move like lightening and
everyone else gets pushed back to let you in. Besides which you are awfullly young to have cancer.  (+ info)

Can benign thyroid nodule become malignant cancer?

---

1) say biopsy shows nodule is benign, fine, but how do i know this will not turn into malignant cancer in future ?

2) should i be repeating biopsy every month or what?

3) and can (numerous) biopsies get the nodule to become malignant?

4) anyone whose biopsy detected benign nodule but this ended up being malignant cancer after some time?
my best friend of 20 years + had exactly the same as this. When she was around 35 she developed a lump in her neck - the doctor did a biopsy and the results came back benign. He gave her the choice, leave the lump there as it is harmless or, have it removed. I told her to have it removed as I wouldn't want a lump in me. So, she gets it removed and as procedure, they test it. They then discover it is cancerous - she goes back in for a major operation to have her whole tyriod removed and is now on tyroxine. Remember that a biopsy only removes a small area of tissue and if that area isn't cancerous then the results will be clear. Hope this helps.  (+ info)

What is the difference between hypothermia and hyperthermia?

---

Hypothermia is an abnormally low body temperature brought on by staying in cold temperatures for a long period of time; a life-threatening emergency.

Hyperthermia is an unusually high body temperature.  (+ info)

What is the -definition- of hyperthermia?

---

How cold does one have to be?

If you slept outside all night in 5C temperatures would that give you hyperthermia?
I believe you mean "hypothermia." Hyperthermia is caused by excessive body heat. To briefly answer your question is answer is yes, hypothermia can develop with prolonged exposure to 5C (41 F).

Hypothermia is defined medically when the body's internal (or core) temperature is 95 degrees (F) or 35 degrees (C). Hypothermia usually comes on gradually. Often, people aren't aware that they need medical attention. Common signs to look for are shivering, which is your body's attempt to generate heat through muscle activity, and the "-umbles" — stumbles, mumbles, fumbles and grumbles. These behaviors may be a result of changes in consciousness and motor coordination caused by hypothermia.

Other signs and symptoms may include:

Slurred speech
Abnormally slow rate of breathing
Cold, pale skin
Fatigue, lethargy or apathy

The severity of hypothermia can vary, depending on how low your core body temperature goes. Severe hypothermia will eventually lead to cardiac and respiratory failure, then death.

Seek immediate medical attention for anyone who appears to have hypothermia. Until medical help is available, follow these guidelines for caring for someone with hypothermia.

Move the person out of the cold. Preventing additional heat loss is crucial. If you're unable to move the person out of the cold, shield the person from the cold and wind as best you can.

Remove wet clothing. If the person is wearing wet clothing, remove it and replace it with a dry covering.

Cover the person's head. Try not to move the person too much. Cut away clothing if you need to.

Insulate the person's body from the cold ground. Lay the person faceup on a blanket or other warm surface.

Monitor breathing. A person with severe hypothermia may appear unconscious, with no apparent signs of a pulse or breathing. If the person's breathing has stopped or appears dangerously low or shallow, begin cardiopulmonary resuscitation (CPR) immediately if you're trained.

Share body heat. To warm the person's body, remove your clothing and lie next to the person, making skin-to-skin contact. Then cover both bodies with a blanket.

Provide warm beverages. If the affected person is alert and is able to swallow, have the person drink a warm, nonalcoholic beverage to help warm the body.  (+ info)

What are the chances that a sessile polyp in the small intestine becomes malignant?

---

My dad is 84 years old and has a one centimeter polyp in the small intestine. Some doctors reccomend surgery while others dont. What are the chances that these polyp becomes malignant?. We are concerned to put him into surgery if it is not really necessary.
Since you are not giving any information about the polyp there is no way of knowing. Your best source for that answer is the pathology report. With that information and questions you ask the surgeons about the basis of their opinions is the best way to make your decision.

If you do decide on surgery he would not need a colostomy.  (+ info)

Can malignant tumors that turn into the spread of metastasis?

---

cause death. if so how long? were talking about different cancers in class and i was just interested.
A malignant tumor that has matastasized is a cancerous tumor that has spread to other areas of the body. Some types of cancer grow and spread more quickly than others. It's not possible to say how long it would take a tumor that has spread to kill someone, because the timeframe depends on so many different things, including the type and location of the cancer.  (+ info)

How are you supposed to treat Neuroleptic malignant syndrome?

---

I had it years ago and it took days for me to recover (the fools at Frimley Park Hospital didn't know what it was).
If I ever got it again, how would they treat it?
Try this link- it seems to explain alot.
