what is the diffrerent between tumour and cancer?

Question

why is it different? how can i tell which is which. which part of cancer is same and which part is different than tumour.

i like to know the mechanisms involving the formation of these two,( tumour & cancer)

what makes cancer fatal

Answer 1

A tumour develops when a group of cell escape from the normal orderly process of cell division and begin to multiply in an uncontrolled way. After a time enough of these abnormal cells will been produced to form a lump, which is called a growth or a tumour.

Tumours may be either benign or malignant. The two important differences between benign and malignant tumours are invasion and spread.

As they grow benign tumours simply push the surrounding normal tissues and organs out of their way. Sometimes pressure from a benign tumour may damage surrounding structures but the benign tumour never actually invades into those structures. By contrast malignant tumours eat into and destroy the normal tissue around them as they increase in size. This means that in some parts of the body benign tumours can grow quite large without causing any problems whereas a malignant tumour damages the tissue around it from the time it first begins to grow.

Benign tumours do not spread. They may grow to a large size but they do not go to other parts of the body. Malignant tumours have the ability to spread by sending off seedlings of tumour which can pass through the blood or lymphatic system to other parts of the body. These seedlings then settle in other organs and form what are called secondary tumours or metastases.

Whilst all malignant tumours have the ability to spread, different tumours vary in the speed with which they do so. Some aggressive malignant tumours begin to spread when they are very very small whilst other slow growing malignant tumours only spread very late in their lives. This means that many malignant tumours are discovered and treated before they have actually had the chance to form secondary tumours.

The word cancer only applies to malignant tumours. There is no such thing as a benign cancer. So, by definition, all cancers are malignant tumours.

The difference between benign and malignant tumours has nothing to do with frequency - in some organs of the body benign tumours are much more common than cancers, nor does it have anything to do with size, some benign tumours can be very large whilst many cancers are quite small.

There are many hundred different types of benign tumour that may develop in our bodies and also several hundred different types of malignant tumour that can occur. These different types of benign and malignant tumours behave in different ways but the fundamental rule that benign tumours never invade or spread always applies

Answer 2

A previously undetected and unexplained lump or bump wherever in the body generally is a tumour (US spelling = tumor). Without difficulty put, a tumour growth may also be either benign or malignant. Whether it is malignant, then it's cancer. Benign tumours are more with ease dealt with in the majority of cases – but should you noticed the Royal Prince Alfred sanatorium application on Channel nine just lately, you possibly can have obvious a fibromatosis that was benign, was once complex for removal and still posed a expertise concern for survival of the sufferer. Malignant tumours are slightly harder to treat seeing that remedy is still in progression closer to finding better treatments with clinical trials. Some malignant tumours ought to be handled with chemotherapy, some with radiotherapy and others with surgical excision. Mixtures of those treatments usually are not uncommon. A caveat to all of that is that some benign tumours have an potential to spread in the body – carcinoid tumour is one example. Even though such benign tumours aren't strictly regarded to be malignant by using definition, the capacity of cells to spread or metastasise via the physique is a function of malignancy. For this reason, some benign tumours can nonetheless rationale issues by way of advantage of growing in different components of the physique. They typically are sluggish growing tumours although and most likely have a good prognosis for the patient.

Answer 3

Tumours are growths located in an isolated place within the body, they are either benign or malignant. benign suggests they have no debilitating effect on the body, and are just growing, when they shouldnt be. and malignant, (which is also referred to as cancer), is the dangerous one, this causes widespread symptoms - which is how cancer is first identified.
the basic principle about formation is just sustained and prolonged cellular growth - all cells have an ability to die, (known as apoptosis), when they are injured or damaged. however cancer cells seem to lose this function - hence the controlled growth. when the cancer spreads from its primarly location to a secondary it is known as metastisis.
hope this helps

Answer 4

Not all tumors are cancerous. Many tumors are benign and not necessarily life threatening. Benign tumors do not spread throughout the body whereas malignant cancerous tumors can spread anywhere in the body. Although many types of cancer involve malignant tumors not all cancers manifest themselves in the form of a tumor. For example leukemia.

Answer 5

A before undetected and unexplained lump or bump everywhere in the physique might nicely be a tumour (US spelling = tumor). in basic terms placed, a tumour strengthen might nicely be the two benign or malignant. regardless of if it relatively is malignant, then it relatively is maximum cancers. Benign tumours are extra certainly taken care of in the final public of situations – yet once you observed the Royal Prince Alfred wellbeing facility application on Channel 9 these days, you've got considered a fibromatosis that became into benign, became into complicated for removing and nonetheless posed a potential issue for survival of the affected person. Malignant tumours are particularly harder to handle simply by fact drugs continues to be in progression in direction of looking extra appropriate remedies with scientific trials. some malignant tumours might desire to be taken care of with chemotherapy, some with radiotherapy and others with surgical excision. mixtures of those remedies are no longer uncommon. A caveat to all of it's that some benign tumours have an potential to unfold in the physique – carcinoid tumour is one occasion. besides the incontrovertible fact that such benign tumours are no longer strictly considered to be malignant via definition, the potential of cells to unfold or metastasise in the direction of the physique is a function of malignancy. for this reason, some benign tumours can nonetheless reason issues via distinctive function of becoming in different components of the physique. they regularly are sluggish becoming tumours nonetheless and regularly have a stable analysis for the affected person.

Answer 6

A tumor is an abnormal mass that grows in your body. It can be benign or malignant. Cancer is a malignant tumor, which means that it can spead to other areas and organs in your body, where it causes damage and usually is eventually fatal if untreated. A benign tumor just continues to grow where it is, and does not spread to other areas.

Answer 7

A tumor can be either malignant or benign. Malignant tumors are cancerous. Benign tumors are not. You cannot tell the difference. A doctor can tell the difference with his/her microscope.

Answer 8

A tumor is a growth that can be either cancerous, or benign. Usually a biopsy is taken of the tumor to determine which it is.

Answer 9

The simple answer is this:

A tumor is defined as any abnormal growth on the body

Not all tumors are malignant (simply bad).

Answer 10

a tumor is what forms(its a mass of cells..yes, it is cancer but its confined usually to a certain area..the mass..ie, a lump or cluster)..cancer is the disease contained with in the mass and once the tumor mastasizes(spelling?) it is a disease coursing through the bloodstream.
