Cancer: Sometimes it's a Shell Game

******
******
I have been chasing the ellusive pea in a shell game, and I am growing cross-eyed!

Those who share my shoes blanche at the usual cancer tropes. My newest personal visualization is not original, but it sums up my fall season.  Monitoring my health has not been a game of medical skill, but of chance and opportunity. With all such slight-of-hands, if you stay focused you can get lucky and track the path of the disease. Take your eyes off the trajectory for a second and the forces will push the "pea" to unexpected destinations. The gamer, as always, is unscrupulous.



June 2011 - "Evolving lymphatic metastasis" / "hypermetabolic focus also seen in the anterior abdominal wall near the base of the umbilicus...soft tissue metastasis cannot be excluded"

...I then started on an aggressive regimen of supplements; bi-weekly high dose IV vitamin C; and weekly ozone infusion treatments...

November 2011 - "July 2011, core biopsy sampling of left axillary lymph node demonstrated metastatic invasive lobular cancer [but at this time] no suspicious abnormalities are identified...may represent positive response to treatment."

...I then tapper off aggressive regimen and opted to do a modified maintenance program of supplements only...veins can only take so much sticking.

August 2012 - Concurrent pneumonia and shingles. Both controlled with broad-based antibiotics.

September 2012 - Sharp intermittent chest pains and shortness of breath unresolved. PCP orders EKG and Chest CT, and refers to pulmonologist and cardiologist.

October  2012 - "Subpleural nodule in the left lower lobe" / "metabolic activity in left axillary"

November 2012 - "Shadow present on right lung...recheck in 2 months with follow up chest CT with contrast"

...Weight loss of 6 lbs over the course of a two plus weeks...Chest pains are now accompanied with nausea and heart burn. Falling asleep curled up in weeble position, propped up because laying on back increases pain. Laying on side makes rib cage feel like its splintering. Not much recuperative sleep happening. Sucks!

November 2012 - "Chronic pericarditis secondary to invasive lobular carcinoma...recheck in 2 months with follow up echocardiagram"

...Restart ozone infusion treatments. Start pounding "Meriva (aka Curcumin") like "skittles" (to challenge the inflammation).  Scheduling IV vitamin C treatments. The game plays on.

S-phase Fraction

Definition: (S faze FRAK-shun) A measure of the percentage of cells in a tumor that are in the phase of the cell cycle during which DNA is synthesized. The S-phase fraction may be used with the proliferative index to give a more complete understanding of how fast a tumor is growing. See mitosis.

Proliferative Index [Synonyms: proliferation index]

Definition: A measure of the number of cells in a tumor that are dividing (proliferating). May be used with the S-phase fraction to give a more complete understanding of how fast a tumor is growing.

Mitosis

Definition: (my-TOE-sis) The process of division (mitotic activity) of somatic cells in which each daughter cell receives the same amount of DNA as the parent cell.
(Phoenix5)

Phenotype

Definition: The appearance of an individual, which results from the interaction of the person's genetic makeup and his or her environment. By contrast, the genotype is merely the genetic constitution (genome) of an individual. For example, if a child's genotype includes the gene for osteogenesis imperfecta (brittle bone disease), minimal trauma can cause fractures. The gene is the genotype, and the brittle bones themselves are the phenotype. (Medicine.Net)

Diploid

Definition: noun - (Science: genetics, cell biology)
A cell or an organism consisting of two sets of chromosomes: usually, one set from the mother and another set from the father. In a diploid state the haploid number is doubled, thus, this condition is also known as 2n. adjective - Of or pertaining to a diploid, that is a cell or an organism with two sets of chromosomes.

Supplement - An example of a cell in a diploid state is a somatic cell. In humans, the somatic cells typically contain 46 chromosomes in contrast to human haploid gametes (egg and sperm cells) that have only 23 chromosomes.  (Biology-Online.org)

Angiogenesis:



 
noun. pl. an·gi·o·gen·e·ses
The formation of new blood vessels.
  • The development of blood vessels is an essential step in tumor growth.
  • A tumor cannot grow larger than a fraction of an inch without a blood supply.
  • Tumor cells produce or cause other cells to produce growth factors that stimulate blood vessel formation.

Angiogenesis Inhibitors:

noun ~ A drug that blocks angiogenesis in cancerous tissue, thus interfering with tumor growth or metastasis.
  • Some cells produce naturally occurring inhibitors of angiogenesis.
  • These inhibitors are a focus of research as possible cancer treatments.
  • Several anti-angiogenesis cancer drugs are already on the market and more are being tested.
  • Angiogenesis inhibitors have two main benefits as a treatment:

    1. They should be less toxic than conventional chemotherapy.
    2. Because they target normal cells and not the cancer cells themselves, they should be less likely to lead to the selection of drug-resistant tumors.

Metastasis
  • Metastasis is the process by which cancer cells spread to distant locations in the body.
  • The majority of death associated with cancer is due to the metastasis of the original tumor cells.
  • Metastasizing cancer cells must secrete a mixture of digestive enzymes in order to degrade barriers.
  • Cancer cells may use the circulatory system to move to a suitable location to settle.
  • Metastasis is a very inefficient process. Most cancer cells die once they leave the original tumor.

Lymphatic Metastasis
  • Cancer can use the lymphatic system as well as the circulatory system to metastasize.
  • The movement of cancer cells via the lymphatic system into lymph nodes is used in the detection of metastatic disease and tumor staging.
