Câncer: uma doença e sua história
Uma doença milenar
Embora exista o registro de um dos mais
antigos tumores no ser humano (um maxilar com sinais de linfoma, datado
como4.000 A.C.), não há um primeiro registro científico inaugural que
fale sobre a doença, pois egípcios, persas e indianos, séculos antes de
Cristo, já faziam menções aos tumores malignos. Mas foi a escola de
medicina de Hipócrates na Grécia (pioneiros por separar a medicina da
magia) que primeiramente definiu a doença como um tumor duro que, muitas
vezes, reaparecia depois de extirpado. Desta época até o século XVI, os
conhecimentos gerais de medicina consideravam que a doença era um
desequilíbrio dos fluídos corpóreos e/ou um desequilíbrio do sistema
linfático.
Somente no século XVIII, com os estudos
do anatomista italiano Giovanni Battista Morgagni somados ao médico
francês Marie François Xavier Bichat, que o câncer passou a ser
entendido de forma diferente. O patologista italiano foi responsável por
caracterizar o câncer como uma unidade específica localizada em uma
parte do corpo e Marie Bichat colaborou para a compreensão que os órgãos
tinham em diferentes tecidos que, por sua vez, eram afetados por
diferentes tipos de câncer. Ainda neste mesmo período o médico Joseph
Claude Anthelme Recamier foi o primeiro a identificar um caso de
metástase causada pela corrente sanguínea ou linfática.
Além dos avanços incipientes da pesquisa
celular, foi somente em 1860 que a doença ganhou um novo patamar com
advento da cirurgia, possibilitado tanto pelo início da utilização de
anestésicos quanto pelas técnicas de assepsia e anti-sepsia criadas pelo
cirrugião Joseph Lister. No final do século XIX, com o aumento dos
conhecimentos de técnicas cirúrgicas e o crescente interesse dos médicos
pela oncologia, começaram a surgir os primeiros casos de sucesso em
procedimentos cirúrgicos como a remoção de um tumor no estômago (1881) e
a mastectomia (1890).
Século XX: institutos e outras ciências a favor da oncologia
A descoberta do fisco alemão Wilhelm
Konrad Roentgen (1845-1923) trouxe uma nova etapa não somente para
estudos do câncer, mas para a medicinaem geral. Aoobservar que a
passagem de uma corrente elétrica em tubos de vácuo produzia uma
radiação capaz de marcar uma chapa fotográfica e atravessar objetos
sólidos, Roentgen criou o raio X. Já nas primeiras décadas do século XX,
o procedimento já era utilizado para tecer diagnósticos sobre tumores e
outras patologias.
A técnica precária da utilização do raio
X fazia com que a elaboração de uma chapa levasse cerca de 30 minutos
para ser concluída. Esse tempo alto de exposição foi visto como um
aspecto negativo, pois gerava irritações e queimaduras na pele dos
pacientes - além de afetar os pesquisadores que trabalhavam com essa
nova tecnologia. Mas ao longo do tempo, alguns médicos observaram que
essas exposições mais intensas também causavam a destruição dos tecidos e
de lesões cancerígenas.
Paralelamente, a cientista Marie Curie
em 1901 descobriu dois novos elementos químicos com uma alta
potencialidade de radiação: Polônio e o Radio. Ao conseguir isolar a
atuação do rádio, a francesa abriu espaço para que outros pesquisadores
pudessem estudar em 1905, o poder do elemento para destruir células
malformadas e destruir tumores malignos. O desenvolvimento de tubos de
raios catódicos (1913) e geradores potentes (1921) conseguiram controlar
a intensidade dos raios e possibilitar sua utilização segura.
O crescimento do interesse científico de
diversas áreas pelo câncer propiciou a fundação de inúmeros centros
especializados como o German Central Committe for Câncer Research na
Alemanha (1900), Americam Assosciation for Câncer (1907) e o Instituto
Radium de Paris (1919) - fundado pelo governo francês e pela Marie
Curie. Com as novas políticas de paz implantadas após o final da
Primeira Guerra Mundial, os países criaram diversas associações de saúde
e institutos específicos para a doença com troca de conhecimentos entre
eles – ação que chegou a inspirar, por exemplo, o surgimento do INCA
(Instituto Nacional do Câncer) no Brasil em 1948.

Cancer: a disease and its history
An age-old disease
Although there is the record of one of the oldest tumors in humans (one jaw with signs of lymphoma, dated como4.000 AC), there is a first inaugural scientific record that talks about the disease, because Egyptians, Persians and Indians centuries before Christ, have made mention of malignant tumors. But it was the school of Hippocratic medicine in Greece (pioneers to separate the medicine of magic) who first defined the disease as a hard tumor that often reappear after excised. From this time until the sixteenth century, general knowledge of medicine believed that the disease was an imbalance of body fluids and / or an imbalance of the lymphatic system.
Only in the eighteenth century, with studies of the Italian anatomist Giovanni Battista Morgagni added to the French physician Marie François Xavier Bichat, that cancer came to be understood differently. The Italian pathologist was responsible for characterizing cancer as a specific unit in a body part and Marie Bichat contributed to the understanding that the bodies were in different tissues that, in turn, were affected by different types of cancer. Also in this same period the doctor Joseph Claude Anthelme Recamier was the first to identify a case of metastasis caused by blood or lymphatic stream.
In addition to the incipient advances in cellular research, it was only in 1860 that the disease has gained a new level with the advent of surgery, made possible both by the early use of anesthesia as by aseptic techniques and antisepsis created by cirrugião Joseph Lister. In the late nineteenth century, with the increase in knowledge of surgical techniques and the growing interest of the medical oncology, began to appear the first cases of successful surgical procedures as the removal of a tumor in the stomach (1881) and mastectomy (1890 ).
Twentieth century: institutes and other sciences in favor of oncology
The discovery of Wilhelm Konrad Roentgen German tax authorities (1845-1923) brought a new stage not only for cancer studies, but for the general medicinaem. Aoobservar that the passage of an electric current in vacuum tubes produced a radiation able to score a photographic plate and pass through solid objects, created the Roentgen Ray X. From the first decades of the twentieth century, the procedure was already used to weave diagnoses of tumors and other pathologies.
The precarious technique using X-ray made the development of a plate took about 30 minutes to complete. This high exposure time was seen as a negative aspect, as generated irritations and burns patients - in addition to affecting the researchers working with this new technology. But over time, some physicians observed that these agents also caused more severe tissue destruction and cancerous lesions.
In parallel, the scientist Marie Curie in 1901 discovered two new chemical elements with a high radiation capability: Polonius and the Radio. When able to isolate the radio performance, the French opened the way for other researchers could study in 1905, the power of the element to destroy malformed cells and destroy malignant tumors. The development of cathode ray tubes (1913) and powerful generators (1921) were able to control the intensity of the rays and allow their safe use.
The growth of scientific interest in various areas by cancer led to the foundation of numerous specialized centers like the German Central Committe for Cancer Research in Germany (1900), Americam Assosciation for Cancer (1907) and the Radium Institute in Paris (1919) - founded by French government and Marie Curie. With the new peace policies implemented after the end of World War II, the countries have various health associations and specialized institutes for the disease with exchange of knowledge between them - action that has come to inspire, for example, the emergence of the INCA (Institute national Cancer) in Brazil in 1948.
