An abnormal mass of tissue that usually does not contain cysts or liquid areas. Solid tumors may be
benign (not cancer)
, or malignant (cancer). Different types of solid tumors are named for the type of cells that form them. Examples of solid tumors are sarcomas, carcinomas, and lymphomas.

What type of cancer is retinoblastoma?
Retinoblastoma is a cancer that starts in the retina, the very back part of the eye. It is the
most common type of eye cancer in children
. Rarely, children can have other kinds of eye cancer, such as medulloepithelioma, which is described briefly below, or ocular (eye) melanoma.
Is lung cancer considered a solid tumor?
“
Solid
tumors,” including cancers of the lung, breast, prostate, colon and rectum, bladder, are not present in large enough numbers in body fluids to be detected with a blood test. However, they may release chemicals that are detectable in body fluids.
Is Wilms tumor a solid tumor?
Common pediatric solid tumor cancers
Neuroblastoma: a cancer usually found in the belly. This type of cancer occurs in infants and young children. Wilms tumor:
a cancer found in one or both kidneys
.
What percentage of cancers are solid tumors?
Solid tumors can be either non-cancerous (benign), pre-malignant (cells that have the potential to become malignant), or malignant (cancerous). Solid tumors represent
approximatively 90% of adult human cancers
.
How do cancers start?
Cancer
develops when the body’s normal control mechanism stops working
. Old cells do not die and instead grow out of control, forming new, abnormal cells. These extra cells may form a mass of tissue, called a tumor.
How aggressive is retinoblastoma?
Summary. Retinoblastoma is an
aggressive eye cancer of infancy and childhood
. Survival and the chance of saving vision depend on severity of disease at presentation. Retinoblastoma was the first tumour to draw attention to the genetic aetiology of cancer.
What is the life expectancy of someone with retinoblastoma?
The 5-year survival rate tells you what percent of children live at least 5 years after the cancer is found. Percent means how many out of 100. The 5-year survival rate for children with
retinoblastoma is 96%
.
Is retinoblastoma curable?
Overall,
more than 9 in 10 children with retinoblastoma are cured
. The chances of long-term survival are much better if the tumor has not spread outside the eye.
Is a hard mass always cancer?
According to the National Cancer Institute, a mass is a lump in the body that can be caused by the abnormal growth of cells, a cyst, hormonal changes or an immune reaction. Fortunately,
a mass is not always cancer.

malignant (cancer)
.
What is the survival rate of Wilms tumor?
The 5-year survival rate for children with a Wilms tumor is
93%
. However, the rate varies according to the stage of the disease. Stage I, II, and III tumors with a favorable histology have a 4-year survival rate that ranges from 95% to 100%. The histology of a tumor is how its cells look under a microscope.
Is Wilms tumor genetic?
Most cases of Wilms tumor
are not caused by inherited genetic factors
and do not cluster in families. Approximately 90 percent of these cancers are due to somatic mutations, which means that the mutations are acquired during a person’s lifetime and are present only in the tumor cells.
Is Wilms tumor aggressive?
But they soon found out her symptoms were caused by something much worse: a Wilms tumor (a type of kidney tumor) with
diffuse anaplasia
(this means cells that are aggressive and resistant to treatment). This is the rarest type of Wilms tumor and the most challenging to overcome.
