What Is Tumor?
Tumors are defined as abnormal growth of the body tissues; a tumor can be benign (non cancerous) or malignant (cancerous). The other names used for tumors are: neoplasm and mass. Usually, a tumor appears due to problems in the cell dividing procedure in an individual's body. Cell division is a strictly controlled procedure; formation of new cells occurs for replacing the older cells or for performing new functions. Normally, cells that have been damaged or are not needed anymore die for allowing healthy cells to replace them. Tumors are mostly formed when this balance between cell division and cell death gets disturbed.
Immune system disorder can be the reason behind formation of tumors. Tumors can also be formed as a result of coming in contact with harmful environmental substances like tobacco, asbestos etc. Some other causes of tumor formation include excessive consumption of alcohol, genetic problems, obesity, inactivity, excessive exposure to sunrays and exposure to chemicals like benzene. Tumor formation is some cases is a result of infections caused by certain viruses; for instance tumors in cancer types like hepatocellular carcinoma and cervical cancer are caused by viruses.
Tumors may or may not produce any symptom. A person experiencing symptoms of tumors might suffer from the following conditions: malaise, fatigue, night sweats, fever accompanied by chills, weight loss and decreased appetite. However, these symptoms tend to vary depending on the tumor's site. The doctor can identify occurrence of a tumor while conducting a physical examination; he then usually recommends the patient to undergo tests like MRI or a CT scan for ensuring that his suspicion is correct. Once these imaging test show that the patient has tumors, a biopsy is done for knowing whether the tumor is benign or malignant. Based on the results of the biopsy, the doctor will decide the mode of treatment suitable for the patient. Treatment methods also tend to vary depending on the location of the tumor.
Tumors that are benign and are situated in a body part where it is unlikely to cause serious symptoms or impair normal body functioning might not require any treatment. There are also instances when benign tumors are operated due to cosmetic reasons. However, doctor often opt for removing benign tumors in the brain due to their delicate location and the possible harmful effect they have on the normal brain tissues. Malignant tumors, on the other hand, are treated using treatment methods like surgery, chemotherapy or radiation therapy; all these methods can also be used together.
Tumour and Cancer
The words cancer and tumour are often the most shocking and most dreaded too. Let us get to know what exactly they are and what the difference between the two is. First of all, we should understand that the word tumour at no point should give us any reason to worry, as every tumour not necessarily be cancerous. This known let us now see what a tumour is.
A tumour is a swelling that is found in the body due to some irregularities in function. Tumours could be benign or non malignant or they could be malignant. But being malignant does not mean it is fatal. Tumour is a term that normally refers to the swellings that we have in the body and are caused usually due to a proliferation of tissues, which happens due to genetic mutations. Not all the neoplasm is the reason for a growth of tumour. Carcinoma [...]
Overview of Cancer
There are millions of people across the world who are suffering from Cancer.
Researchers are trying to find out the reasons through which cancer is caused and how it actually spreads. They are trying to find out methods that would ensure that cancer is detected and prevented easily and also is thus treated. So these researchers are constantly in the process of improving the quality of life for the people who are affected with cancer.
Cancer takes its origin in the cells, and these are the major building blocks that actually form the tissue. These tissues are the ones that totally make up the organs of the entire body. Cells normally grow and also divide to form more new cells and the body uses these cells. When the cells become old they die and then new cells are born in their place. [...]
Signs of Maxillary Sinus Tumors
Maxillary sinuses are glands located behind our cheekbones. Occurrence of tumors in the maxillary sinuses is common. According to the definition presented by the National Cancer Institute, tumors are masses consisting of extra tissues, which are formed with newly produced cells that are created without any need. Tumors can be benign or malignant. A benign tumor is usually not known for causing any health issue. A person will suffer from severe health problems due to benign tumors only if these tumors impede the sinus drainage or block the airflow. The malignant tumors, on the other hand, are formed of cancerous cells. As the disease progresses, the malignant tumor in the maxillary sinuses tends to spread outside the sinus glands affecting tissues of other body parts. Below, we have discussed [...]

Deadly Brain Tumor’s Forte might also be Its Achilles heel
Malignant gliomas are a prevalent sub-form of primary brain tumor and among the most lethal form. Despite on-going advancement being made in the treatment of other forms of solid tumor cancer types, the highly belligerent type of malignant glioma known as GBM (glioblastoma multiforme) has persistently resisted neurosurgery advancements, radiotherapy and varied conservative or new-fangled medications.
However a global research group helmed by LICR scientists at the Univ. of California, San Diego School of Medicine have reported in the mid-Aug edition of ‘Genes & Development’ that they have uncovered a novel signalling path in-between the GBM cells which in case finally obstructed or hampered can considerably slacken or lower tumor development and malignance.
GBMs surpass several [...]
Expelling the Fear of Colonoscopy Procedure
The near future of colonoscopy procedure would be state-of-the-art mini robotics camera ingestion for probing any dubious growths in the colon. However, in the present times, the ideal method for screening colon cancer still continues to be the comparatively basic colonoscopy procedure.
A 4 foot spanning, fine, bendable fiber optic tube (half inch diameter-wise) is employed for looking into the interiors of the large intestine beginning from the rectal area and concluding in the initial portion of the colon (or known as cecum) or collectively known as the large bowel area. The scope would also emit air bursts inside the colon for expanding it to facilitate better viewing. It is an outpatient method for evaluating signs such as pains in the abdomen, bleeding from rectum, polyp formations [...]
Identification And Treatment Overview Of Gestational Trophoblastic Tumors
The preliminary signs of GTD or gestational trophoblastic tumors could be tricky to ascertain as few of them replicate normal gestation signs. The prevalent signs comprise of bleeding from the vagina that must be alerted to the doctor no sooner does it occur. Other signs could be:
Undue swell up of the abdomen when pregnant.
Pain felt in the abdomen.
Becoming anemic.
Pre-eclampsia (toxaemia).
A hyper active thyroid gland leading to hyperthyroidism.
Diagnosis & Tests
For diagnosing GTD, the doctor would advice the below mentioned testing:
Blood Analysis
Tests for analysing the blood usually comprise of doing a CBC or complete blood count along with measuring the levels of HCG or human chorionic gonadotropin that are usually high in case pregnant, however unusually elevated [...]
The Rare Desmoid Tumors
Desmoid tumor is an atypical cancer form developing in the tissue which form sinews generally noted in the arm, leg or abdominal area and at times in the chest region. Such tumors are additionally known as aggressive fibromastosis that are deemed non-malignant as they classically do not metastasize to other body parts. Such tumors could infect closely placed tissues and organs, and curbing them could become tricky.
Thought the reason for such tumors arising is unclear, scientists have uncovered that those kids having a family past of a heritable colon cancer known as polyposis coli are more susceptible to developing desmoids tumor. Treatment alternatives comprise of surgery, radiation and chemotherapy based on the placing of the tumor and how old the infant is.
Desmoid Tumor Symptoms
Desmoid [...]
Wilms’ Tumor Treatment Options
Wilms’ Tumor is treated employing the prevalent approaches of surgery, radiation and chemotherapy on the basis of the staging of the cancer and the overall health of the child.
Surgery
This widely used treatment in case of Wilms’ Tumor is conducted in any of the below mentioned ways:

The method involves the surgical removal of the cancer and a section of the kidney just adjoining the cancer. It classically is performed solely in exceptional situations like in a scenario where there has been damage to the other kidney or has previously been taken out.
Simple Nephrectomy
This method involves complete removal of a kidney after which the second kidney would be donning the task of blood purification process.
Radical Nephrectomy
This method is carried out [...]
Deciphering Neuroblastomas
Neuroblastoma is a belligerent malignant tumor observed during infancy and younger aged kids, originating in the sympathetic nerve tissues that are accountable for handling the body’s crisis management plan of fighting and getaway reaction. There are nearly six hundred diagnoses of children annually in the U.S. alone and is the most widespread form of tumor inflicting below one year old infants.
Though these tumor could be present in the child when he is born, these tumors mostly go undetected till they have proliferated and begun exerting pressure on the adjacently placed organs or have metastasized to the lymph nodes, the CNS (central nervous system), bones or the bone marrow. Atypically, neuroblastoma could be identified prior to the child being born when the expectant mother undergoes [...]
Ewing’s Sarcoma
Ewing’s Sarcoma is a cancer mostly observed to affect the arms and legs, especially the thigh bone. The muscle and soft tissues adjoining the tumor could additionally be affected. Frequently found during adolescence in the age groups of ten to twenty years and occurring in or near the bone. There could be metastasis of the Ewing’s sarcoma cells to other regions of the body inclusive of the bone marrow and the lungs.
Ewing’s sarcoma is observed to affect both the sexes equally prior to them turning adolescents. However, subsequent to entering adolescence, men have a somewhat greater likelihood of developing the cancer as compared to women because of the augmented growth rate in men when they reach puberty.
